* [avih] a custom build dir fix for lib/Makefileseyko2016-05-201-4/+4
| | | | | | | | | | | mkdir build; cd build ../configure && make ../../lib/libtcc1.c:31: error: include file 'stddef.h' not found Author: Avi Halachmi Date: Sat Nov 14 18:40:36 2015 +0200 When building from the root tcc dir, $TOP and $top_srcdir are the same, but with a custom build dir, we need top_srcdir

* Reorganize the source tree.gus knight2015-07-271-8/+8
| | | | | | | | | | * 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...

* fix installation amd bcheck for Windowsseyko2015-04-102-10/+25
| | | | | | | | | | | | | | | | | | | | | | * 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.
* a small revers for bcheck.o changes (d80593bc4d43)seyko2015-03-301-1/+1
| | | | | | replacing (addr > e->size) with (addr >= e->size) was correct only in one place, a second replacing is reversed by this commit.
* Fix for Microsoft compilersseyko2015-03-291-1/+1
| | | | | Miccrosoft Visual Sudio (Express) 2008 and 2010 do not accept variable definitions C99 style, reported by Fabio <oldfaber@gmail.com>
* fix for the bcheck.o (bug #14958)seyko2015-03-291-13/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | - 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

* libtcc1.a while "configure --enable-cross"seyko2015-03-201-1/+1
| | | | | build and install libtcc1.a for i386, x86_64 and arm64 (libtcc1.a for x86_64 was not installed on i386)

* lib/Makefile: Partial revert of 896a0c881ac3.Edmund Grimley Evans2015-03-101-1/+0
| | | | lib/lib-arm64.c must be compiled by tcc.
* 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
* 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.
* arm64: Implement __clear_cache.Edmund Grimley Evans2015-03-081-1/+1
| | | | | | __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
* partial revert of the commit 4ad186c5ef61seyko2015-03-041-0/+14

* build-libtcc1-by-tcc: use a new tcc to compile a libtcc1.c and alloca.Sseyko2015-03-041-7/+0
| | | | | | | This will allow to build a libtcc1.a even if a bootstrap compiler don't support a target arch. There was alrady this feature but only for OS Darwin.

* Don't build libtcc1 with -fstack-protector-strongMatteo Cypriani2014-09-071-0/+4
| | | | | | | Prevent libtcc1.a to be compiled with -fstack-protector-strong, so that linking with tcc doesn't fail because symbol '__stack_chk_fail_local' is not present in libtcc1.a. This is useful only if the CFLAGS passed from the main Makefile contain this flag.
* Fix mistake. Change jb by jbe. tiny c round (INT_MAX = 0x7FFFFFFF) to a ↵Carlos Montiers2014-07-103-3/+3

* build: add initial NetBSD support.minux2014-04-121-2/+2
| | | | | | | | | | | | Not able to generate ELF files on NetBSD yet (lacks the note and crt1.o is actually named crt0.o on NetBSD), but -run works with these extra defines: -D__lint__ -D"__symbolrename(x)=asm(#x)" -D__NetBSD__ The -D__lint__ is an ugly hack, TCC should be able to emulate GCC just fine, but it seems TCC doesn't support __builtin_va_list yet? typedef __builtin_va_list __va_list; /usr/include/sys/ansi.h:72: error: ';' expected (got "__va_list")

| | | | | gcc/mingw produces msvc compatible pecoff objects, tcc only knows ELF.
* arm: Provide alloca()Michael Matz2014-04-052-2/+13
| | | | | | This provides a simple implementation of alloca for ARM (and enables the associated testcase). As tcc for ARM doesn't contain an assembler, we'll have to resort using gcc for compiling it.
* shared libs: Build libtcc1.a with -fPICMichael Matz2014-04-021-1/+5
| | | | | TCCs runtime library must be compiled as position independend code, so it can be linked into shared libraries.
* Create bcheck region for argv and arge argumentThomas Preud'homme2014-03-291-0/+7
| | | | | | | | | | | For program manipulating argv or arge as pointer with construct such as: (while *argv++) { do_something_with_argv; } it is necessary to have argv and arge inside a region. This patch create regions argv and arge) if main is declared with those parameters.

* Make condition in libtcc1 based on targetThomas Preud'homme2014-03-091-5/+5
| | | | | | Prior to this commit runtime library was compiled according to the host because of the macro used to detec what architecture to choose. This commit fixes this by using the TARGET_* macro instead.

* i386: use __fixdfdi instead of __tcc_cvt_ftolgrischka2014-01-061-18/+21
| | | | | | | | | | | | Variants __fixsfdi/__fixxfdi are not needed for now because the value is converted to double always. Also: - remove __tcc_fpinit for unix as it seems redundant by the __setfpucw call in the startup code - avoid reference to s->runtime_main in cross compilers - configure: fix --with-libgcc help - tcctok.h: cleanup
* Fix signed integer division in ARM runtime ABIThomas Preud'homme2013-12-151-9/+21
| | | | | | | | - fix computation of absolute value (clearing the sign bit does not since integers are encoded in 2's complement) - test sign of integer in a more conventional way (binary and with the high bit does not work for long long due to a bug in gtst) - spacing in include
