* configure: --config-musl/-uClibc switch & misc cleanupsgrischka2017-05-131-1/+0
| | | | | | | | | | | | | | | - configure: - add --config-uClibc,-musl switch and suggest to use it if uClibc/musl is detected - make warning options magic clang compatible - simplify (use $confvars instead of individual options) - Revert "Remove some unused-parameter lint" 7443db0d5f841b81a55e918bf8c228dd20f9ddb2 rather use -Wno-unused-parameter (or just not -Wextra) - #ifdef functions that are unused on some targets - tccgen.c: use PTR_SIZE==8 instead of (X86_64 || ARM64) - tccpe.c: fix some warnings - integrate dummy arm-asm better
* Remove some unused-parameter lintLarry Doolittle2017-05-081-0/+1
| | | | | | | | Mark TCCState parameter as unused in tcc_undefine_symbol(), tcc_add_symbol(), tcc_print_stats(), asm_get_local_label_name(), use_section1(), tccpp_delete(), tcc_tool_ar(), tcc_tool_impdef(), and tcc_tool_cross(). Also mark it unused in tcc_add_bcheck() unless CONFIG_TCC_BCHECK. Remove it entirely in ld_next().
* Spelling fixes in C comments onlyLarry Doolittle2017-05-071-2/+2

* Tidy unary() a bitMichael Matz2017-05-021-1/+4
| | | | | | factor code a bit for transforming tokens into SValues. This revealed a bug in TOK_GET (see testcase), which happened to be harmless before. So fix that as well.
* Simple-minded fix for bug #50847Larry Doolittle2017-04-251-1/+2
| | | | | | bug #50847: #line directive corrupts #include search path Keep a second copy of the filename, that isn't changed by the #line directive, and use that on the initial search path for #include files.
* final adjustments for releasegrischka2017-04-251-1/+31
| | | | | | | | | | | | | | | | | | | | | - configure/Makefiles: minor adjustments - build-tcc.bat: add -static to gcc options (avoids libgcc_s*.dll dependency with some mingw versions) - tccpe.c/tcctools.c: eliminate MAX_PATH (not available for cross compilers) - tccasm.c: use uint64_t/strtoull in unary() (unsigned long sometimes is only uint32_t, as always on windows) - tccgen.c: Revert (f077d16c) "tccgen: gen_cast: cast FLOAT to DOUBLE" Was a rather experimental, tentative commit, not really necessary and somewhat ugly too. - cleanup recent osx support: - Makefile/libtcc.c: cleanup copy&paste code - tccpp.c: restore deleted function
* tcc: fixup clang warningsAndrei Warkentin2017-04-251-31/+2
| | | | | | | | | | | The O(xxx) stuff in i386-asm.c had me scratching my head. Extracting the macro and trying it out in a separate program doesn't give me any warnings, so I'm confused about what could be going on there. Any cast will make things happy. I used a uint64_t to catch actual cases of overflow, which will still cause a -Wconstant-conversion warning. Signed-off-by: Andrei Warkentin <andrey.warkentin@gmail.com>
* tccpp: Fix corner case of fnlike macro invocationMichael Matz2017-04-151-2/+4
| | | | | | | Arg substitution leaves placeholder marker in the stream for empty arguments. Those need to be skipped when searching for a fnlike macro invocation in the replacement list itself. See testcase.
* mems & leaksgrischka2017-02-131-6/+10
| | | | | | | | | | | | - define_start: set above preprocess_start because now preprocess_start is defining macros. - free "cmd_include_files" - free defines always (after error-longjmps) - close all files (after error-longjmps) - tccpe.c: free imports always - libtcc.c: call tcc_memstats only after all states have been deleted.
* fixes & cleanupsgrischka2017-02-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - tccgen.c/tcc.h: allow function declaration after use: int f() { return g(); } int g() { return 1; } may be a warning but not an error see also 76cb1144ef91924c53c57ea71e6f67ce73ce1cc6 - tccgen.c: redundant code related to inline functions removed (functions used anywhere have sym->c set automatically) - tccgen.c: make 32bit llop non-equal test portable (probably not on C67) - dynarray_add: change prototype to possibly avoid aliasing problems or at least warnings - lib/alloca*.S: ".section .note.GNU-stack,"",%progbits" removed (has no effect) - tccpe: set SizeOfCode field (for correct upx decompression) - libtcc.c: fixed alternative -run invocation tcc "-run -lxxx ..." file.c (meant to load the library after file). Also supported now: tcc files ... options ... -run @ arguments ...
* Fix pseudo leakMichael Matz2016-12-201-5/+6
| | | | | | Once-allocated buffers (here a string) that aren't explicitely freed at program end but rather freed at _exit about 1 nanosecond later are regarded a leak with MEM_DEBUG, so explicitely free it. Blaeh :-/
* libtcc.c: -m option cleanupgrischka2016-12-181-2/+2
| | | | | | | | | | | handle mms-bitfields as sub-options of -m. (-mfloat-abi is still special because it requires arguments) tcc.c: help(): - list -mms-bitfields under 'Target specific options' libtcc.c/MEM_DEBUG - add check for past buffer writes
* tests: add memory leak testgrischka2016-12-181-16/+19
| | | | | | | | | | | | | Also ... tcctest.c: - exclude stuff that gcc doesn't compile on windows. libtcc.c/tccpp.c: - use unsigned for memory sizes to avoid printf format warnings - use "file:line: message" to make IDE error parsers happy. tccgen.c: fix typo
* tccpp: Fix token pastingMichael Matz2016-12-151-7/+8
| | | | | | | | | See testcase. We must always paste tokens (at least if not currently substing a normal argument, which is a speed optimization only now) but at the same time must not regard a ## token coming from argument expansion as the token-paste operator, nor if we constructed a ## token due to pasting itself (that was already checked by pp/01.c).
* tccasm: Don't ignore # in preprocessor directivesMichael Matz2016-12-151-21/+24
| | | | | | | Our preprocessor throws away # line-comments in asm mode. It did so also inside preprocessor directives, thereby removing stringification. Parse defines in non-asm mode (but retain '.' as identifier character inside macro definitions).
* tccpp: Allow computed include like 42.hMichael Matz2016-12-151-26/+19
| | | | | | The include directive needs to be parsed as pp-tokens, not as token (i.e. no conversion to TOK_STR or TOK_NUM). Also fix parsing computed includes using quoted strings.
* tccpp: Implement __BASE_FILE__ macroMichael Matz2016-12-151-0/+6
| | | | | Like __FILE__ but always refers to the command line file name also from inside headers.
* Implement -include cmdline optionMichael Matz2016-12-151-0/+14
| | | | | | This option includes a file as if '#include "file"' is the first line of compiled files. It's processed after all -D/-U options and is processed per input file.
* tccpp: Fix macro_is_equalMichael Matz2016-12-151-4/+5
| | | | | | | When tokens in macro definitions need cstr_buf inside get_tok_str, the second might overwrite the first (happens when tokens are multi-character non-identifiers, see testcase) in macro_is_equal, failing to diagnose a difference. Use a real local buffer.
* tccpp: free defines also with PP_BENCHMichael Matz2016-12-151-1/+3
| | | | | When benchmarking preprocessing of multiple files we need to free the defines like when not benchmarking.
* tccgen: fix inline_functions double free fixgrischka2016-11-111-10/+15
|
* tccgen: inline_functions double free fixgrischka2016-11-111-2/+1
| | | | | | Fix double free of the inline function token_string which could happen when an error/longjmp occurred while compiling the inline function.
* tccpp_new/delete and other cleanupsgrischka2016-10-171-4/+7
|
* tccpp : "tcc -E -P" : suppress empty linesgrischka2016-10-091-7/+13
| | | | | | | | | Also: - regenerate all tests/pp/*.expect with gcc - test "insert one space" feature - test "0x1E-1" in asm mode case - PARSE_FLAG_SPACES: ignore \f\v\r better - tcc.h: move some things
* tccpp: no cache for include if #elif seengrischka2016-10-041-8/+9
| | | | | | | | #ifndef guards are cached, however after #elif on the same level, the file must be re-read. Also: preprocess asm as such even when there is no assembler (arm).
* tccpp: parse_line_comment: fix possible buffer overrungrischka2016-10-011-3/+3
|
* tccpp: allow "0x1e+1" in asmgrischka2016-10-011-9/+13
|
* tccpp: token ## pasting: preserve parts if pasting failsgrischka2016-10-011-10/+12
| | | | | | | | | for example #define LBL(name) _ ## name ## : LBL(main) will give two tokens '_main' and ':' and the warning
* Revert "-fnormalize-inc-dirs"grischka2016-10-011-1/+0
| | | | | | | Too much code. gcc 3.x doesn't have that either. This reverts commit 41785a0bf9d505a3647a10ddc330417f52fd4528. This reverts commit 21665f433890e2038626f0b3123b189a62a67dc9.
* tcc -E: add one space in cases: tiny solutiongrischka2016-10-011-52/+20
| | | | | | replaces f5f82abc99424c4ece836000934fcf57a867c635 Also: fix tcc flags in Makefile, fix tcc -E
* tccpp: cleanupgrischka2016-10-011-69/+101
| | | | | | | | | | | | | | | | - "utf8 in identifiers" from 936819a1b90f2618bb3f86730189cf2895948ba0 - CValue: remove member str.data_allocated - make tiny allocator private to tccpp - allocate macro_stack objects on heap because otherwise it could crash after error/setjmp in preprocess_delete():end_macro() - mov "TinyAlloc" defs to tccpp.c - define_push: take int* str again
* libtcc: cleanup @listfilegrischka2016-10-011-15/+0
| | | | | | | | | Also: - allow more than one item per line - respect "quoted items" and escaped quotes \" (also for LIBTCCAPI tcc_setoptions) - cleanup some copy & paste
* tccpp: #pragma once: make it workgrischka2016-10-011-35/+23
| | | | | | | | | | | after several "fixes" and "improvements" b3782c3cf5e66f74207303c381a305daabccdb12 5fb57bead41cd3a84f0aa3f98d00b5fe5de25a08 feature did not work at all - Use 'once' flag, not 'ifndef_macro' - Ignore filename letter case on _WIN32 - Increment global pp_once for each compilation
* tccpp: restore -D symbols for multiple sourcesgrischka2016-10-011-14/+16
| | | | | | | | | | | | | | | ... also for built-in defines The case: $ tcc -D FOO a.c b.c with // a.c #undef FOO // b.c #ifndef FOO # error -D FOO has been lost #endif

| | | | | | | | | | | fixes 5c35ba66c5ade4713bbd9c005e66889f6d7db293 Implementation was consistent within tcc but incompatible with the ABI (for example library functions vprintf etc) Also: - tccpp.c/get_tok_str() : avoid "unknown format "%llu" warning - x86_64_gen.c/gen_vla_alloc() : fix vstack leak
* Redo "fix line number in macro redefined message"grischka2016-05-251-5/+2

* tcc -E -P10 : output all numbers as decimalsgrischka2016-05-121-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This may be used to preprocess Fabrice Bellards initial revision in this repository to demonstrate its capability to compile and run itself (on i386 32-bit linux or windows). Initial revision: 27f6e16bae9d0f73acec07f61aea696ab5adc680 Also needed: * an empty stdio.h * a wrapper named tc.c with void expr(void); void decl(int); void next(void); #include "tcc.c" * an hello.c such as int main() { printf("Hello World\n"); return 0; } All files with unix LF only lines. Then ... * preprocess the source $ tcc -E -P10 -I. tcc.c -o tc1.c * compile the compiler $ tcc -w -I. tc.c -o tc -ldl * run it to compile and run itself to compile and run itself to compile and run itself to compile and run hello.c $ ./tc tc1.c tc1.c tc1.c hello.c --> Hello World! ------------------------------------------------------ * On i386 windows this may be added to the tc.c wrapper #ifdef _WIN32 #include <windows.h> void *dlsym(int x, const char *func) { if (0 == strcmp(func, "dlsym")) return &dlsym; return GetProcAddress(LoadLibrary("msvcrt"), func); } #endif
* Insert spaces between certain tokens when tcc is invoked with -E.Edmund Grimley Evans2016-05-091-1/+53
| | | | | | Insert a space when it is required to prevent mistokenisation of the output, and also in a few cases where it is not strictly required, imitating GCC's behaviour.
