* ability to specify a type of the input file with the -x switchseyko2015-04-121-19/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | Usage example: tcc -xc ex5.cgi From a gcc docs: You can specify the input language explicitly with the -x option: -x language Specify explicitly the language for the following input files (rather than letting the compiler choose a default based on the file name suffix). This option applies to all following input files until the next -x option. Possible values for language are: c c-header c-cpp-output c++ c++-header c++-cpp-output objective-c objective-c-header objective-c-cpp-output objective-c++ objective-c++-header objective-c++-cpp-output assembler assembler-with-cpp ada f77 f77-cpp-input f95 f95-cpp-input java -x none Turn off any specification of a language, so that subsequent files are handled according to their file name suffixes (as they are if -x has not been used at all)
* -fdollar-in-identifiers switch which enables '$' in identifiersseyko2015-04-121-0/+1
| | | | | | | | | | library Cello: http://libcello.org/ which uses `$` and several variations of as macros. There is also RayLanguage which also uses it as a macro for a kind of ObjC style message passing: https://github.com/kojiba/RayLanguage This is a patch from Daniel Holden.
* replace a method to force bcheck.o linkingseyko2015-04-121-5/+8
| | | | | | * define __bound_init as external_global_sym insteed of the compiling a tiny program * remove warning about buf[] when CONFIG_TCC_BCHECK is not defined
* Fix for Microsoft compilersseyko2015-04-111-1/+1
| | | | | | | Correction for the commit db08122d31a681e593c6679140d2df0cc63c8784 As pointed Thomas Preud'homme buf[] may be used outside of the block whit code: name = block;
* option to use an old algorithm of the array in struct initializationseyko2015-04-101-0/+1
| | | | | | This is for a case when no '{' is used in the initialization code. An option name is -fold-struct-init-code. A linux 2.4.26 can't find initrd when compiled with a new algorithm.
* fix a preprocessor for .Sseyko2015-04-101-1/+4
| | | | | | Lets assume that in *.S files a preprocessor directive follow '#' char w/o spaces between. Otherwise there is too many problems with the content of the comments.
* fix a preprocessor for .Sseyko2015-04-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | * tell a right line number in error message if a #line directive is wrong * don't print an error message if we preprocess a .S file and #line directive is wrong. This is the case of the # 4026 bytes comment in *.S file. * preprocess_skip: skip a line with if (parse_flags & PARSE_FLAG_ASM_COMMENTS) p = parse_line_comment(p); if line starts with # and a preprocessor command not found. A test program: #if defined(CONFIG_EDD) || defined(CONFIG_EDD_MODULE) # This repeats until either a device doesn't exist, or until #endif * remove a second definition of the TOK_FLAG_* and PARSE_FLAG_* from the tccpp.c
* fix installation amd bcheck for Windowsseyko2015-04-101-0/+11
| | | | | | | | | | | | | | | | | | | | | | * define targetos=Windows when --enable-tcc32-mingw, --enable-cygwin, ... * use TARGETOS insteed HOST_OS when selecting PROGS * use "$(tccdir)" insteed $(tccdir) on install (spaces in path) * install tcc.exe too * produce bcheck.o when cross-compiling too (lib/Makefile) * force bcheck.o linking by compiling inside tcc_set_output_type() a dummy program with local array. Otherwise bcheck.o may be not linked. * replace %xz format specifier with %p in bcheck (don't supported on Windows) * call a __bound_init when __bound_ptr_add, __bound_ptr_indir, __bound_new_region, __bound_delete_region called. This is because a __bound_init inside ".init" section is not called on Windows for unknown reason. * print on stderr a message when an illegal pointer is returned: there is no segmentation violation on Windows for a program compiled with "tcc -b" * remove "C:" subdir on clean if $HOST_OS = "Linux" * default CFLAGS="-Wall -g -O0" insteed CFLAGS="-Wall -g -O2" to speed up compilation and more precise debugging.

* fix the bug #31403: parser bug in structureseyko2015-04-101-0/+1
| | | | | | - a warning: unnamed struct/union that defines no instances - allow a nested named struct declaration w/o identifier only when option -fms-extensions is used
* Fix for Microsoft compilersseyko2015-03-291-1/+1

* fix for a -dumpversion option: move it before -dDseyko2015-03-231-2/+2
| | | | | | | Options must be sorted and a long one must preceed a short one. What was before: tcc -dumpversion tcc: error: invalid option -- '-dumpversion'

* fix to allow build tcc by build-tcc.batseyko2015-03-191-0/+2
| | | | | move call to print_defines() from tcc.c to the libtcc.c define a print_defines() as a ST_FUNC
* Turn on a implicit-function-declaration warning by default.seyko2015-03-031-0/+1
| | | | | | | | A non declared function leads to a seriuos problems. And while gcc don't turn this warning on lets tcc do it. This warning can be turned off by -Wno-implicit-function-declaration option. And autor must explicitly do this if program must be compiled with this warning off.
* -std=c99 option for the tcc: allow to use a tcc as a reference compiler for ↵seyko2015-03-031-0/+6

* A gcc preprocessor option -dD addedseyko2015-03-031-0/+10
| | | | | | | | | With this option on a defines are included into the output (inside comments). This will allow to debug a problems like: In file included from math.c:8: In file included from /usr/include/math.h:43: /usr/include/bits/nan.h:52: warning: NAN redefined
* Added a gcc preprocessor options -P, -P1seyko2015-03-031-0/+5
| | | | | | | | | | | tcc -E -P do not output a #line directive, a gcc compatible option tcc -E -P1 don't follow a gcc preprocessor style and do output a standard #line directive. In such case we don't lose a location info when we going to compile a resulting file wtith a compiler not understanding a gnu style line info.

* libtcc.c (put_extern_sym2): Extend the scope of buf to match its useLee Duhem2014-12-111-2/+1
| | | | | After leaving the code block that `buf' is defined, `buf' will not exist, so `name' will point to a variable that does not exist.
* tccgen: nocode_wanted: do not output constantsgrischka2014-08-011-1/+0
| | | | | | | | | | | | | | | | | | | | This for example suppresses string constants such as with int main() { return sizeof "foo"; } Actually, setting nocode_wanted = 1; in libtcc.c for the initial global level seemed wrong, since obviously "nocode_wanted" means code as any side effects, also such as string constants. This reverts a part of 2de1b2d14cc920e2c698ff0086f5558c2da7f569 (documented as "Some in-between fixes" in Changelog)
* win64: try to fix linkagegrischka2014-06-241-1/+0
| | | | | | | | | - revert to R_X86_64_PC32 for near calls on PE - revert to s1->section_align set to zero by default Untested. Compared to release_0_9_26 the pe-image looks back to normal. There are some differences in dissassembly (r10/r11 usage) but maybe that's ok.
* tccpe: adjust for new 'hidden' symbols featuregrischka2014-04-171-7/+5
| | | | | in order to avoid conflicts with windows specific (ab)usage of the Elf32_Sym -> st_other field.
* Parse assembler .hidden directiveMichael Matz2014-04-141-0/+3
| | | | | This makes TCCs assembler understand the '.hidden symbol' directive (and emits a STV_HIDDEN ELF symbol then).
* tcc, libtcc: fix build on windows with latest mingw.minux2014-04-111-1/+1

* tests2: cleanupgrischka2014-04-071-8/+1
| | | | | | | | | - remove -norunsrc switch Meaning and usage (-run -norun...???) look sort of screwed. Also general usefulness is unclear, so it was actually to support exactly one (not even very interesting) test This partially reverts e31579b0769e1f9c0947d12e83316d1149307b1a
* Declare wint_t in <stddef.h> when neededMichael Matz2014-04-071-0/+9

* be stricter with aliasinggrischka2014-01-071-4/+4
| | | | | | | | | | | | | | Refactoring (no logical changes): - use memcpy in tccgen.c:ieee_finite(double d) - use union to store attribute flags in Sym Makefile: "CFLAGS+=-fno-strict-aliasing" basically not necessary anymore but I left it for now because gcc sometimes behaves unexpectedly without. Also: - configure: back to mode 100755 - tcc.h: remove unused variables tdata/tbss_section - x86_64-gen.c: adjust gfunc_sret for prototype
* misc. fixesgrischka2014-01-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | - tccgen: error out for cast to void, as in void foo(void) { return 1; } This avoids an assertion failure in x86_64-gen.c, also. also fix tests2/03_struct.c accordingly - Error: "memory full" - be more specific - Makefiles: remove circular dependencies, lookup tcctest.c from VPATH - tcc.h: cleanup lib, include, crt and libgcc search paths" avoid duplication or trailing slashes with no CONFIG_MULTIARCHDIR (as from 9382d6f1a0e2d0104a82ed805207d9e742c6b068) - tcc.h: remove ";{B}" from PE search path in ce5e12c2f950052d8109b6b7a56d900547705c08 James Lyon wrote: "... I'm not sure this is the right way to fix this problem." And the answer is: No, please. (copying libtcc1.a for tests instead) - win32/build_tcc.bat: do not move away a versioned file
