* tccpp: cleanup options -dD -dM, remove -Cgrischka2016-05-051-36/+14
| | | | | | | The lexer is for reading files, not for writing. Also : - macro_is_equal(): avoid crash if redefining __FILE__
* tccgen: scope levels for local symbolsgrischka2016-05-051-1/+0
| | | | | | | | | | | | | | | | | | ... for fast redeclaration checks Also, check function parameters too: void foo(int a) { int a; ... } Also, try to fix struct/union/enum's on different scopes: { struct xxx { int x; }; { struct xxx { int y; }; ... }} and some (probably not all) combination with incomplete declarations "struct xxx;" Replaces 2bfedb18675228c3837c23fa523231f55e102c12 and 07d896c8e5d1b46bf4aebd403c78e5f7ffebe02a Fixes cf95ac399cbce1ea8a519f91dd36a5cfd4ea7943
* -fno-type-redefinition-checkseyko2016-05-041-0/+1
| | | | | | | | | | | | | don't catch redefinition for local vars. With this option on tcc accepts the following code: int main() { int a = 0; long a = 0; } But if you shure there is no problem with your local variables, then a compilation speed can be improved if you have a lots of the local variables (50000+)
* section alignmentseyko2016-04-221-1/+1
| | | | | | Alignment of unknown sections changed from 32 to PTR_SIZE This is gcc/pcc default value. This helps to use tcc as linux kernel compiler.
* Improve hash performanceVlad Vissoultchev2016-04-171-7/+8
| | | | | | | | | | | | - better `TOK_HASH_FUNC` - increases `hash_ident` initial size to 16k (from 8k) - `cstr_cat` uses single `realloc` + `memcpy` - `cstr_cat` can append terminating zero - `tok_str_realloc` initial size to 16 (from 8) - `parse_define` uses static `tokstr_buf` - `next` uses static `tokstr_buf` - fixes two latent bugs (wrong deallocations in libtcc.c:482 and tccpp.c:2987)
* allow to compile tcc by pccseyko2016-04-151-1/+1
| | | | | * pcc have only __linux__ macro (and no __linux) * pcc don't have __clear_cache proc
* preprocessor oprtion -C (keep comments)seyko2016-04-151-0/+20
| | | | | This is done by impression of the pcc -C option. Usual execution path and speed are not changed.
* Simplify @listfiles parsingVlad Vissoultchev2016-04-131-39/+17
| | | | This moves listfiles parsing inline in `tcc_parse_args1`
* Allow tcc arguments to be read from @listfilesseyko2016-04-131-27/+84
| | | | | | | | | | | | | | | | | From: Vlad Vissoultchev Date: Tue, 12 Apr 2016 20:43:15 +0300 Subject: Allow tcc arguments to be read from @listfiles This allows all @ prefixed arguments to be treated as listfiles containing list of source files or tcc options where each one is on a separate line. Can be used to benchmark compilation speed with non-trivial amount of source files. The impl of `tcc_parse_args` had to be moved to a new function that is able to be called recursively w/ the original one remaining as a driver of the new one. Listfiles parsing happens in a new `args_parser_add_listfile` function that uses `tcc_open`/`tcc_close/inp` for buffered file input.
* Implement -dM preprocessor option as in gccVlad Vissoultchev2016-04-061-2/+4
| | | | | | There was already support for -dD option but in contrast -dM dumps only `#define` directives w/o actual preprocessor output. The original -dD output differs from gcc output by additional comment in front of `#define`s so this quirk is left for -dM as well.
* -fnormalize-inc-dirsseyko2016-04-031-0/+93
| | | | | | remove non-existent or duplicate directories from include paths if -fnormalize-inc-dirs is specified. This will help to compile current coreutils package
* tccpp: cleanup #include_nextgrischka2015-11-201-92/+0
| | | | | | | | | | | | | | | | tcc_normalize_inc_dirs: normally no problem to be absolutly gcc compatible as long as it can be done the tiny way. This reverts to the state before recent related commits and reimplements a (small) part of it to fix the reported problem. Also: Revert "parsing "..." sequence" c3975cf27c792d493e76a2058a1eaf588324053e && p[1] == '.' is not a reliable way to lookahead
* tccgen: asm_label cleanupgrischka2015-11-201-1/+1
| | | | | | | - avoid memory allocation by using its (int) token number - avoid additional function parameter by using Attribute Also: fix some strange looking error messages

* normalize inc dirs, symplify include_nextseyko2015-11-051-0/+80
| | | | | | | | | include dirs are prepared as in gcc - for each duplicate path keep just the first one - remove each include_path that exists in sysinclude_paths include_next streamlined by introducing inc_path_index in the BufferedFile

* Reorganize the source tree.gus knight2015-07-271-2322/+0
| | | | | | | | | | * Documentation is now in "docs". * Source code is now in "src". * Misc. fixes here and there so that everything still works. I think I got everything in this commit, but I only tested this on Linux (Make) and Windows (CMake), so I might've messed something up on other platforms...
* Clean up lots of rogue tabs.gus knight2015-07-271-9/+9
| | | | | | Still some more tabs to be taken care of. arm-gen.c and tcccoff.c have so many style issues that I'm just going to throw clang-format at them.

* redo of the -dD optionseyko2015-05-131-1/+16

* tccpp: fix issues, add testsgrischka2015-05-091-55/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * fix some macro expansion issues * add some pp tests in tests/pp * improved tcc -E output for better diff'ability * remove -dD feature (quirky code, exotic feature, didn't work well) Based partially on ideas / researches from PipCet Some issues remain with VA_ARGS macros (if used in a rather tricky way). Also, to keep it simple, the pp doesn't automtically add any extra spaces to separate tokens which otherwise would form wrong tokens if re-read from tcc -E output (such as '+' '=') GCC does that, other compilers don't. * cleanups - #line 01 "file" / # 01 "file" processing - #pragma comment(lib,"foo") - tcc -E: forward some pragmas to output (pack, comment(lib)) - fix macro parameter list parsing mess from a3fc54345949535524d01319e1ca6378b7c2c201 a715d7143d9d17da17e67fec6af1c01409a71a31 (some coffee might help, next time ;) - introduce TOK_PPSTR - to have character constants as written in the file (similar to TOK_PPNUM) - allow '\' appear in macros - new functions begin/end_macro to: - fix switching macro levels during expansion - allow unget_tok to unget more than one tok - slight speedup by using bitflags in isidnum_table Also: - x86_64.c : fix decl after statements - i386-gen,c : fix a vstack leak with VLA on windows - configure/Makefile : build on windows (MSYS) was broken - tcc_warning: fflush stderr to keep output order (win32)

* 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.

* 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.
