vbcc is (c) in 1995-96 by Volker Barthelmann (cga68k): changes in the code generator for amiga68k (cla68k): changes in the C library for amiga68k (vca68k): changes in the compiler frontend for amiga68k Changes since V0.3a - vc.lib/vcs.lib/mieee.lib/m881.lib/m040.lib/vbcc/vc rebuilt - div/ldiv should be conforming now - ungetc should now work even if it is the first action to a stream (cla68k) - fflush(0) only affects files in output mode (cla68k) - removed const qualifier from the ctype-array (cla68k) - changed the ctype-functions to use the array (cla68k) - added #definition of NULL to stdio.h (hope that's correct) (cla68k) - changed several stdio-functions and added line-buffering (cla68k) - bug fixed: setbuf/setvbuf was broken (cla68k) - bug fixed: vbrowse didn't ask for gadtools.library V39 - vbrowse opens a window that fits on a standard workbench by default now - bug fixed: there was a bug in newmalloc.c (cla68k) - bug fixed: included new version of the pooled memory routines for amiga.lib and rebuilt amiga.lib; hopefully works with OS2.0 now (cla68k) - bug fixed: struct-declaration-structs have been freed too early; current solution is not very nice, but should work - bug fixed: there should not be restrictions on the source layout any more (problem with look-ahead fixed) - bug fixed: identifiers longer than MAXI could cause problems - bug fixed: passing incomplete types to functions without prototypes did not cause a diagnostic - changed the internal representation of structs/unions/prototypes - some non-conforming things in the source corrected - hardcoded limit for struct sizes etc. eliminated - type of incomplete structs should be ok now - bug fixed: code after an always false if etc. wasn't generated even if it contained a label Changes since V0.3 - vc passes options starting with -D or -I through to the preprocessor - the format for -pp/-ppv has changed (vca68k) - vc writes names of objects for the linker to a temporary file if they are very long (vca68k) - vc supports option -nostdlib to prevent linking with standard-startup/libs additional entries -l2/-l2v are necessary in vc.config (vca68k) - bug fixed: perror was called prerror in the library - ouch; Make-scripts changed and vc.lib/vcs.lib rebuilt (cla68k) - bug fixed: perror-prototype was incorrect (cla68k) - added missing prototype for strerror() to string.h (cla68k) - added missing prototype for strtok() to string.h (cla68k) - rebuilt amigas.lib and vcs.lib (cla68k) - bug fixed: constant data in code-sections was addressed via a4 with -sd (cga68k) - bug fixed: conversion between pointers and integers may not be omitted in most cases (cga68k) - branches after TEST unsigned are changed now and tst may be omitted (cga68k) - rebuilt amiga.lib (cla68k) - bug fixed: fd2lib didn't work with varargs-functions expecting the argument-list in a data register (cla68k) - added several varargs-functions to fd2lib (cla68k) - edited the Make#?lib.scripts (cp->copy, *.c->#?.c) (cla68k) - added a few xdefs to amiga.lib (cla68k) Changes since V0.2v - changed the version number :-) Changes since V0.2u - rebuilt vc.lib and vcs.lib - bug fixed: the vbcc-compiled cpp did not close opened files; now the routines in mysupport.c close all opened files at exit - bug fixed: there was still an error that caused wrong line numbers to be printed in messages when an external preprocessor was used - compiling with NO_OPTIMIZER #defined and linking without av.o, cp.o, cse.o, flow.o, loop.o and rd.o produces a smaller executable that doesn't include the global optimizer - compiled the cpp from the lcc-distribution with vbcc and changed vc.config to call this one rather than dcpp (vca68k) - bug fixed: removed some float.h scratch from limits.h (cla68k) - bug fixed: some code generation errors fixed (cga68k) - bug fixed: addressing-modes were sometimes used where they shouldn't (cga68k) - bug fixed: sometimes wrong code was generated for a op= b; expressions - bug fixed: some optimizer routines sometimes called mymalloc(0) which caused mymalloc to abort with C-libraries returning a null pointer; fixed by changing the size to 1 in mymalloc (not very nice, but simple) - added alternative malloc-routines that use the Amiga's AllocPooled-Rotuines (libsrc/stdlib/newmalloc) (cla68k) - bug fixed: in the handling of switch-statements the addressing-mode-pointers were set to zero too early and therefore later overwritten with scratch - bug fixed: in some places memory that was already free'd was accessed under certain circumstances - replacing multiplications by shifts was not done in recent versions (cga68k) - some minor code generation improvements (cga68k) - bug fixed: copies of local auto variables of inlined functions got non-empty identifiers which caused corrupt code generation under certain circumstances - bug fixed: function-inlining didn't work with return-values that must be passed via pointer - bug fixed: variables in IDENTIFIER-nodes were searched with find_var() in gen_code() again, rather than using a copy from type_expression(); this generated corrupt code in certain cases of function-inlining - rebuilt showerr and tovbr using small-data with new PhxLnk - added special inlining of strlen() and strcpy() - bug fixed: the amiga68k code generator assumed long-alignment with inline_memcpy - bug fixed: tst may not be omitted if operand is unsigned (cga68k) - bug fixed: inline_memcpy was not only used when optimizing - bug fixed: the line number displayed in diagnostics were sometimes wrong if an external preprocessor with # <line> "file" was used - bug fixed: function inlining messed up labels of static local vars Changes since V0.2t - removed any 060-specific modulo-handling again (060 has div?l.l) (cga68k) - some minor code generation improvements with arithmetic instructions and constants (cga68k) - warning for not correctly handled empty struct-declarations added - bug fixed: initializations of incomplete structs resulted in infinite error loops - improved diagnostics regarding incomplete types - bug fixed: nested calls to inlined functions were broken - address-of instructions are subject to common-subexpression-elimination - bug fixed: function-inlining sometimes assigned the arguments to the wrong variables - #pragma only-inline on/off added - some associativity optimizations are done with ADDI2P, too Changes since V0.2s - some minor changes and bug fixes on vbrowse - program showerr added - bug fixed: if the return value was moved to an address register this was supposed to set the condition codes (cga68k) - addq #const,a7 is no longer supposed to destroy condition-codes (cga68k) - bug fixed: sometimes the popping of function arguments was moved before a call (cga68k) - added #pragma type to display the type of an expression - bug fixed: declarations of functions within functions were buggy in 0.2r, because the prototype of the inner function was freed to early - bug fixed: vbcc assumed that "fmove.l fpx,ea" sets condition-codes for ea (cga68k) - bug fixed: TEST-instructions were omitted even if the type was different (could probably only happen with dirty things) (cga68k) - bug fixed: offsets for temporary buffers for scratch-registers were sometimes incorrectly calculated (only without optimizing); scanf() of the recent mieee.lib and m040.lib versions was broken due to that bug - bug fixed: string constants are only allowed as initalizers for array of char now - bug fixed: handling of long float/double is now a bit better - changed flags of a few error messages - bug fixed: problem with unexpected end of file errors fixed and some improvements in killsp() and translation_unit() - function calls are never separated from the corresponding PUSHs now (this might confuse the delayed popping of code-generators) - if all successors of a block have the same instruction at the beginning it is moved to the predecessor in certain cases - space for local variables is better used in optimizing compilation now - function inlining doesn't increase label-numbers any more - handling of local registers and pointer dereferencing improved a bit (temporary vars that get dereferenced should almost always be assigned a proper register now) - bug fixed: rearranging of array-accesses was buggy in 0.2s - bug fixed: a previous declaration of a function was not visible in the function definition in 0.2s - changed the ctype macros a bit (cla68k) - bug fixed: use of addressing modes was buggy in 0.2s (therefore the last mieee.lib was broken) (cga68k) - code generation for modulo improved for 020+ (incl. 060) (cga68k) Changes since V0.2r - bug fixed: conversions between unsigned<->floating point should now always be correct with mieee.lib (cga68k) (cla68k) mieee.lib rebuilt - if -noasm is specified the .asm file is no longer created - gen_vars() now does not create output if there were errors or -noasm was specified (this also fixes a bug that created infinite internal errors after certain corrupt initializers) - bug fixed: vbcc did not correctly recognize if opening of the input file failed in V0.2q/r - some optimizations to improve array accesses - VARADR objects are subject for copy propagation now - add/sub with constant addresses gets folded (opt only) - divsl.l is not used when -cpu=68060 is selected (cga68k) - switch-statements can be implemented by SUB/TEST/BEQ sequences rather than COMPARE/BEQ sequences (selectable with SWITCHSUBS) - bug fixed: no error for duplicate case labels was printed - bug fixed: detecting of loops did identify loops with jumps out of the loop as normal loops - bug fixed: scope of function prototypes should now be correct - bug fixed: function parameters were not marked as DEFINED and therefore redefinition of function parameters did not cause errors Changes since V0.2q - if several basic blocks have the single same successor and the last last instruction of those statements is identical it is moved to the common successor - for CPUs>=68040 8bit constants are not copied to registers (cga68k) - popping of function arguments is done one instruction before a TEST inst. (I thought this was necessary to avoid certain tst-instructions, because my manual says addq #x,a7 changes condition codes - however this seems to be wrong) (cga68k) - Thorsten Schaaps' preprocessor integrated into vbcc files vbpp.h and preproc.c added - new options: - -nested-comments allows nested comments (not ANSI conforming) - -cpp-comments allows C++ style comments (not ANSI conforming) - -macro-redefintion allows redefinition of macros (not ANSI conforming) - -no-trigraphs prevents expansion of trigraphs (not ANSI conforming) - -no-preprocessor prevents use of the bultin preprocessor - -E only preprocesses the file to <file>.i Changes since V0.2p - bug fixed: strncat() did not append a 0, but behaved like strncpy (cla68k) - bug fixed: sizeof(uncomplete type) did not cause an error message - bug fixed: wrong code was generated for ?: if the condition evaluated to a scratch-var pointing somewhere - bug fixed: pointer:0 and 0:pointer was not allowed in conditional-exp - bug fixed: delayed popping produced wrong code with nested function calls - support for #line directive of most preprocessors added - several additions made to must_convert() (cga68k) - realloc() added to vc.lib (cla68k) - target-specific optimization options have been separated from the -O flag - the Amiga68k code generator now accepts the following flags to replace the former corresponding flags in the -O option: (cga68k) - -use-framepointer - -no-addressing-modes - -no-delayed-popping - bit 12 (4096) in -O activates function inlining; previously defined functions are inlined in their caller, depending on the size of the function - new option -inline-size can be used to in-/decrease the number of functions to be inlined; default=30 - higher values mean more functions get inlined Changes since V0.2n/0.2o - new option -optpasses=n sets the maximum number of optimizer passes - bug fixed: ADDI2P with a short integer sometimes was not converted if the target was a data register - constant data is placed in the code sections as long as -const-in-data is not specified (cga68k) - m040.lib started (cla68k) - unnecessary tst instructions are sometimes eliminated (cga68k) - constants -128<=x<128 are not copied in a register for SETRETURN and PUSH - COMPARE x,#0 should now always be converted to TEST x - bug fixed: a label-statement at the end of a block caused an error - bug fixed: sometimes still used type node was freed in alg_opt - bug fixed: unsigned function arguments were sometimes converted to signed - calling scheme for ieee and ldiv functions changed (cga68k) - usage of addressing modes with ieee and ldiv functions prohibited (cga68k) - bug fixed: files opened for append were deleted, oops (cla68k) - use of addressing modes slightly changed (cga68k) - modf, ldexp and frexp added to mieee.lib and m881.lib (cla68k) - bug fixed: unsigned integers were not allowed in case labels - bug fixed: push problem - bug fixed: cmp x,#0 was sometimes converted to tst x without changing the following branching instruction (cga68k) - for and while loops are generated differently when optimizing is activated (first testing of the loop condition can sometimes be deleted) - bug fixed: isquickkonst2 now tests for 0<x<=8 rather than 0<=x<=8 (ouch) (cga68k) - a>>0=a<<0=a and a few other algebraic optimizations added - insert_const2() added and insert_const() changed - saverestoreregs() now has a stack for the pushed register-lists (cga68k) (removed again, because saveregs/restoreregs has now been removed and mechanism changed) - bug fixed: delayed popping of function arguments corrected (cga68k) - delayed popping and omitting of framepointer can now be turned on separately (256 for framepointer, 512 for delayed popping) - bug fixed: stackoffset was sometimes incorrectly calculated - internal mechanism for passing function return values changed, structure returns should be reentrant now some library routines may have to be recompiled mieee.lib was rebuilt to use the new mechanism (cla68k) - op a,b->scratchvar;
