Aranda Gutierrez) +- better _Bool lvalue support (signaled by Alex Measday) +- function parameters must be converted to pointers (signaled by Neil Brown) +- sanitized string and character constant parsing +- fixed comment parse (signaled by Damian M Gryski) + +version 0.9.16: + +- added assembler language support +- added GCC inline asm() support +- fixed multiple variable definitions : uninitialized variables are + created as COMMON symbols. +- optimized macro processing +- added GCC statement expressions support +- added GCC local labels support +- fixed array declaration in old style function parameters +- support casts in static structure initializations +- added various __xxx[__] keywords for GCC compatibility +- ignore __extension__ GCC in an expression or in a type (still not perfect) +- added '? :' GCC extension support + +version 0.9.15: + +- compilation fixes for glibc 2.2, gcc 2.95.3 and gcc 3.2. +- FreeBSD compile fixes. Makefile patches still missing (Carl Drougge). +- fixed file type guessing if '.' is in the path. +- fixed tcc_compile_string() +- add a dummy page in ELF files to fix RX/RW accesses (pageexec at + freemail dot hu). + +version 0.9.14: + +- added #warning. error message if invalid preprocessing directive. +- added CType structure to ease typing (faster parse). +- suppressed secondary hash tables (faster parse). +- rewrote parser by optimizing common cases (faster parse). +- fixed signed long long comparisons. +- fixed 'int a(), b();' declaration case. +- fixed structure init without '{}'. +- correct alignment support in structures. +- empty structures support. +- gcc testsuite now supported. +- output only warning if implicit integer/pointer conversions. +- added static bitfield init. + +version 0.9.13: + +- correct preprocessing token pasting (## operator) in all cases (added + preprocessing number token). +- fixed long long register spill. +- fixed signed long long '>>'. +- removed memory leaks. +- better error handling : processing can continue on link errors. A + custom callback can be added to display error messages. Most + errors do not call exit() now. +- ignore -O, -W, -m and -f options +- added old style function declarations +- added GCC __alignof__ support. +- added GCC typeof support. +- added GCC computed gotos support. +- added stack backtrace in runtime error message. Improved runtime + error position display. + +version 0.9.12: + +- more fixes for || and && handling. +- improved '? :' type handling. +- fixed bound checking generation with structures +- force '#endif' to be in same file as matching '#if' +- #include file optimization with '#ifndef #endif' construct detection +- macro handling optimization +- added tcc_relocate() and tcc_get_symbol() in libtcc. + +version 0.9.11: + +- stdarg.h fix for double type (thanks to Philippe Ribet). +- correct white space characters and added MSDOS newline support. +- fixed invalid implicit function call type declaration. +- special macros such as __LINE__ are defined if tested with defined(). +- fixed '!' operator with relocated address. +- added symbol + offset relocation (fixes some static variable initializers) +- '-l' option can be specified anywhere. '-c' option yields default + output name. added '-r' option for relocatable output. +- fixed '\nnn' octal parsing. +- fixed local extern variables declarations. + +version 0.9.10: + +- fixed lvalue type when saved in local stack. +- fixed '#include' syntax when using macros. +- fixed '#line' bug. +- removed size limit on strings. Unified string constants handling + with variable declarations. +- added correct support for '\xX' in wchar_t strings. +- added support for bound checking in generated executables +- fixed -I include order. +- fixed incorrect function displayed in runtime error. + +version 0.9.9: + +- fixed preprocessor expression parsing for #if/#elif. +- relocated debug info (.stab section). +- relocated bounds info (.bounds section). +- fixed cast to char of char constants ('\377' is -1 instead of 255) +- fixed implicit cast for unary plus. +- strings and '__func__' have now 'char[]' type instead of 'char *' + (fixes sizeof() return value). +- added __start_xxx and __stop_xxx symbols in linker. +- better DLL creation support (option -shared begins to work). +- ELF sections and hash tables are resized dynamically. +- executables and DLLs are stripped by default. + +version 0.9.8: + +- First version of full ELF linking support (generate objects, static + executable, dynamic executable, dynamic libraries). Dynamic library + support is not finished (need PIC support in compiler and some + patches in symbol exporting). +- First version of ELF loader for object (.o) and archive (.a) files. +- Support of simple GNU ld scripts (GROUP and FILE commands) +- Separated runtime library and bound check code from TCC (smaller + compiler core). +- fixed register reload in float compare. +- fixed implicit char/short to int casting. +- allow array type for address of ('&') operator. +- fixed unused || or && result. +- added GCC style variadic macro support. +- optimized bound checking code for array access. +- tcc includes are now in $(prefix)/lib/tcc/include. +- more command line options - more consistent handling of multiple + input files. +- added tcc man page (thanks to Cyril Bouthors). +- uClibc Makefile update +- converted documentation to texinfo format. +- added developper's guide in documentation. + +version 0.9.7: + +- added library API for easy dynamic compilation (see libtcc.h - first + draft). +- fixed long long register spill bug. +- fixed '? :' register spill bug. + +version 0.9.6: + +- added floating point constant propagation (fixes negative floating + point constants bug). + +version 0.9.5: + + - uClibc patches (submitted by Alfonso Martone). + - error reporting fix + - added CONFIG_TCC_BCHECK to get smaller code if needed. + +version 0.9.4: + + - windows port (currently cannot use -g, -b and dll functions). + - faster and simpler I/O handling. + - '-D' option works in all cases. + - preprocessor fixes (#elif and empty macro args) + - floating point fixes + - first code for CIL generation (does not work yet) + +version 0.9.3: + + - better and smaller code generator. + - full ISOC99 64 bit 'long long' support. + - full 32 bit 'float', 64 bit 'double' and 96 bit 'long double' support. + - added '-U' option. + - added assembly sections support. + - even faster startup time by mmaping sections instead of mallocing them. + - added GNUC __attribute__ keyword support (currently supports + 'section' and 'aligned' attributes). + - added ELF file output (only usable for debugging now) + - added debug symbol generation (STAB format). + - added integrated runtime error analysis ('-g' option: print clear + run time error messages instead of "Segmentation fault"). + - added first version of tiny memory and bound checker ('-b' option). + +version 0.9.2: + + - even faster parsing. + - various syntax parsing fixes. + - fixed external relocation handling for variables or functions pointers. + - better function pointers type handling. + - can compile multiple files (-i option). + - ANSI C bit fields are supported. + - beginning of float/double/long double support. + - beginning of long long support. + +version 0.9.1: + + - full ISOC99 initializers handling. + - compound literals. + - structures handle in assignments and as function param or return value. + - wide chars and strings. + - macro bug fix + +version 0.9: + - initial version. |
