* fix a preprocessor for .Sseyko2015-04-102-19/+15
| | | | | | | | | | | | | | | | | | | | | | | | * 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 Windowsseyko2015-04-107-39/+70
| | | | | | | | | | | | | | | | | | | | | | * 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.
* handle a -s option by executing sstrip/strip programseyko2015-04-103-1/+18

* output all sections if we produce an executable fileseyko2015-04-101-0/+1
| | | | | | | | | | tcc w/o -g option generate an executable file which format is not recognized by binutils. It is like stripped one but binutils don't think so. Solution: generate not stripped file which can be correctly stripped by external utils. may be there is a need to handle a -s option and call a sstrip/strip program to do a job.
* remove a compilation warnings for libtest and test3seyko2015-04-102-0/+4

| | | | | | | | | | | | | | | | | | | | | | | | | | | - care about __attribute__ redefinition in the system headers - an invalid pointer must be returned when (addr >= e->size), and not (addr > e->size) A test program: #include <stdio.h> #include <stdlib.h> int main () { int v[10]; fprintf(stderr, "&v[0] = %p\n", &v[0]); fprintf(stderr, "&v[10] = %p\n", &v[10]); exit(1); return 0; } // tcc -b test.c The output before a patch: &v[0] = 0xbf929d8c &v[10] = 0xbf929db4 The output after a patch: &v[0] = 0xbff6e33c &v[10] = 0xfffffffe

* quick fix for the native tcc on debian/ubuntuseyko2015-03-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Force to use a NATIVE_DEFINES insteed of the DEFINES for the native tcc.

* restore a linux 2.4.26 kernel compilation (commit 5bcc3eed7b93 correction)seyko2015-03-201-1/+5
| | | | | | | | The following check in tccgen.c is removed if (nocode_wanted) tcc_error("statement expression in global scope"); This check is introduced in commit 5bcc3eed7b93 and breaks compilation of the linux 2.4.26 kernel.
* correction for the previous commitseyko2015-03-201-2/+2
| | | | use "x86-64" as a directory name for the libtcc1.a installation when cross-compiling.
* libtcc1.a while "configure --enable-cross"seyko2015-03-202-7/+10
| | | | | build and install libtcc1.a for i386, x86_64 and arm64 (libtcc1.a for x86_64 was not installed on i386)

* tccgen.c: (!nocode_wanted) -> (nocode_wanted) in arm64 part.Edmund Grimley Evans2015-03-101-2/+2

* Add some missing nocode_wanted guardThomas Preud'homme2015-03-104-16/+30
| | | | | | int i = i++ causes a segfault because of missing guard. Looking recursively at all backend functions called from middle end several more guard appeared to be missing.
* lib/Makefile: Partial revert of 896a0c881ac3.Edmund Grimley Evans2015-03-101-1/+0
| | | | lib/lib-arm64.c must be compiled by tcc.
* A correction for the commit: revert a grischka patch: gdb refused to know "main"seyko2015-03-101-0/+7
| | | | | keep revert (check SHF_ALLOC) only for x86 target and keep a grishka patch for other targets
* don't use a *-tcc to compile *.S files for ARM*seyko2015-03-101-0/+2
| | | | | A tcc for ARM* don't have an assembler. This is partial reverse of the commit build-libtcc1-by-tcc: use a new tcc to compile a libtcc1.c and alloca.S
* A native tcc for MSYS (Windows) must be i386-win-tcc.exe and not i386-tcc.exeseyko2015-03-102-1/+17
| | | | | i386-tcc.exe is a compiler for i386 Linux. A HOST_OS variable in Makefile is introduced and used to select a native compiler (which one to name as tcc.exe)
* x86-64: Fix stdarg for large non-float structsMichael Matz2015-03-091-4/+3
| | | | | | | | | | Some structs are passed in registers. When they need more than one the implementation of __va_arg on x86-64 didn't correctly account for this. This fixes only the cases where the structs consist of integer types, as there the register save area is consecutive. Fixes some tests from 73_arm64.c, but still leaves those failing that use floating point in the large-but-regpassed structs.
* Remove incorrect commentMichael Matz2015-03-091-2/+0
| | | | Not the code was confused, I was :)
* Find libtcc1.a on arm32Michael Matz2015-03-091-1/+1
| | | | The directory is called "arm", not "ARM".
* Fix stack overwrite on structure returnMichael Matz2015-03-097-17/+26
| | | | | | | | | The common code to move a returned structure packed into registers into memory on the caller side didn't take the register size into account when allocating local storage, so sometimes that lead to stack overwrites (e.g. in 73_arm64.c), on x86_64. This fixes it by generally making gfunc_sret also return the register size.
* arm64: Implement __clear_cache.Edmund Grimley Evans2015-03-085-1/+63
| | | | | | __clear_cache is defined in lib-arm64.c with a single call to __arm64_clear_cache, which is the real built-in function and is turned into inline assembler by gen_clear_cache in arm64-gen.c
* tests/Makefile: Quote to avoid: /bin/sh: 1: [: !=: unexpected operatorEdmund Grimley Evans2015-03-071-1/+1
