* | Add __clear_cache implementation in libtcc1Thomas Preud'homme2013-11-053-2/+36
| | | | | | | | Add __clear_cache function for flushing caches to libtcc1.
* | Fix allocation of struct in registers on ARMThomas Preud'homme2013-11-051-46/+44
| | | | | | | | | | | | | | | | | | | | | | Allocation of struct in core and/or VFP registers on ARM is made by manipulating the value stack to create 3 distinct zones: parameters allocated on stack, parameters of type struct allocated in core registers and parameters of type struct allocated in VFP registers. Parameters of primitive type can be in any zone. This commit change the order of the zones from stack, VFP, core to stack, core, VFP (from highest addresses to lowest ones) in order to correctly deal the situation when structures are allocated both in core and VFP registers.
* | Revert "Add support for thread-local storage variables"Thomas Preud'homme2013-11-035-54/+14
| | | | | | | | | | | | | | | | | | | | TLS support in tinyCC is absolutely not ready: - segment register not select in load and store - no relocation added for computing offset of per-thread symbol - no support for TLS-specific relocations - no program header added as per Drepper document about TLS This reverts commit 1c4afd13501f07a673aed5f130166f2ee0f30927.

* | Fix CONFIG_TCC_SYSINCLUDEPATHS on !win32 systemsRamsay Jones2013-10-021-2/+4
| | | | | | | | | | | | | | | | | | | | | | Commit 9382d6f1 ("Fix lib, include, crt and libgcc search paths", 07-09-2013) inadvertently included an initial empty entry to the CONFIG_TCC_SYSINCLUDEPATHS variable (for non win32 targets). In addition to an empty line in the 'tcc -vv' display, this leads to the preprocessor attempting to read an include file from the root of the filesystem (i.e. '/header.h').

* | Generate an error when a function is redefinedThomas Preud'homme2013-09-162-1/+9
| | | | | | | | | | | | | | | | | | Use one more bit in AttributeDef to differenciate between declared function (only its prototype is known) and defined function (its body is also known). This allows to generate an error in cases like: int f(){return 0;} int f(){return 1;}
* | win32: fix libtcc supportgrischka2013-09-102-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For "tcc -run file.c", I was trying to initialize the FP control in a function in libtcc1.a (_runmain) before calling main. Unfortunately that turned out to cause problems with for example libtcc_test since such usage doesn't necessarily define a 'main' function. So for tcc -run we're back to relying on the FP control word that is set in the startup code of tcc.exe rsp. libtcc.dll. This fixes part of commit 73faaea227a53e365dd75f1dba7a5071c7b5e541

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Use runtime function for conversion - Also initialize fp with tcc -run on windows This fixes a bug where double x = 1.0; double y = 1.0000000000000001; double z = x < y ? 0 : sqrt (x*x - y*y); caused a bad sqrt because rounding precision for the x < y comparison was different to the one used within the sqrt function. This also fixes a bug where printf("%d, %d", (int)pow(10, 2), (int)pow(10, 2)); would print 100, 99 Unrelated: win32: document relative include & lib lookup win32: normalize_slashes: do not mirror silly gcc behavior This reverts part of commit 8a81f9e1036637e21a47e14fb56bf64133546890 winapi: add missing WINAPI decl. for some functions

* Relicensing TinyCCgrischka2013-05-051-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | It has been discussed on the list whether it would be good to relicense TinyCC under a more permissive BSD-like license. The discussion started here: http://lists.gnu.org/archive/html/tinycc-devel/2013-04/msg00052.html Opinions varied but mostly were positive so it appears to be worth to start the process and see how far we can get. For that purpose I've committed a new file RELICENSING with the suggested new license clause and a list for people to confirm their agreement (or disagreement). If you have contributed to TinyCC in the past, in particular if you are one of the copyright owners for an entire file, please add yourself to that file (rsp. replace the question mark) and commit the change to the "mob" brancn with log message: Relicensing TinyCC Thanks.
* ARM hardfloat: fix struct return with float/double argsDaniel Glöckner2013-05-011-0/+1

* Improved variable length array support.James Lyon2013-04-2712-23/+311
| | | | | | | | | | | | | | | VLA storage is now freed when it goes out of scope. This makes it possible to use a VLA inside a loop without consuming an unlimited amount of memory. Combining VLAs with alloca() should work as in GCC - when a VLA is freed, memory allocated by alloca() after the VLA was created is also freed. There are some exceptions to this rule when using goto: if a VLA is in scope at the goto, jumping to a label will reset the stack pointer to where it was immediately after the last VLA was created prior to the label, or to what it was before the first VLA was created if the label is outside the scope of any VLA. This means that in some cases combining alloca() and VLAs will free alloca() memory where GCC would not.
* Fixed x86-64 long double passing.James Lyon2013-04-264-123/+206
| | | | | | long double arguments require 16-byte alignment on the stack, which requires adjustment when the the stack offset is not an evven number of 8-byte words.
* Fixed silly error in Windows build of tests (abitest-cc not linking to libtcc)James Lyon2013-04-262-33/+34
| | | | | | | | I really should do this when less tired; I keep breaking one platform while fixing another. I've also fixed some Windows issues with tcctest since Windows printf() uses different format flags to those on Linux, and removed some conditional compilation tests in tcctest since they now should work.
* Fixed i386 calling convention issue and CMake build on i386.James Lyon2013-04-263-6/+19
| | | | | The i386 calling convention expects the callee to pop 1 word of the stack when performing a struct ret.
* Sorted out CMake on x86-64 and fixed silly XMM# bug introduced when working ↵James Lyon2013-04-2510-38/+110
| | | | | | | | | on Win64 stdargs. I removed the XMM6/7 registers from the register list because they are not used on Win64 however they are necessary for parameter passing on x86-64. I have now restored them but not marked them with RC_FLOAT so they will not be used except for parameter passing.
* Added cross compilation to CMake build system.James Lyon2013-04-256-112/+263
| | | | | Brings it more into line with make based system. I've tested on 32- and 64-bit Windows, but not yet Linux.
* 64-bit tests now pass (well, nearly).James Lyon2013-04-248-142/+295
| | | | | tcctest1-3 fail, but this appears to be due to bugs in GCC rather than TCC (from manual inspection of the output).
* Added CMake build system (to facilitate Win64 builds)James Lyon2013-04-215-4/+254
| | | | | | Win32 build and tests work under CMake, however I haven't added install code yet. Win64 build fails due to chkstk.S failing to assemble.
* Workaround for MinGWs use of 80-bit long double on Win32.James Lyon2013-04-192-8/+27
| | | | | | This is incompatible with MSVC and TCC on Win32. Bounds checking appears to be broken (test4).
* Fixed 64-bit integer bug introduced by x86-64 ABI work.James Lyon2013-04-192-13/+12
| | | | Now I need to check that the x86-64 stuff still works.
* Improved x86-64 XMM register argument passing.James Lyon2013-04-192-76/+119
| | | | | | | Also made XMM0-7 available for use as temporary registers, since they are not used by the ABI. I'd like to do the same with RSI and RDI but that's trickier since they can be used by gv() as temporary registers and there isn't a way to disable that.
* Fixed problems with XMM1 use on Linux/x86-64.James Lyon2013-04-193-112/+120
| | | | | | All tests pass. I think I've caught all the cases assuming only XMM0 is used. I expect that Win64 is horribly broken by this point though, because I haven't altered it to cope with XMM1.
* Most x86-64 tests now work; only on error in test1-3.James Lyon2013-04-193-67/+129
| | | | | | I've had to introduce the XMM1 register to get the calling convention to work properly, unfortunately this has broken a fair bit of code which assumes that only XMM0 is used.
* Got test1-3 working on x86-64.James Lyon2013-04-194-85/+197
| | | | | | There are probably still issues on x86-64 I've missed. I've added a few new tests to abitest, which fail (2x long long and 2x double in a struct should be passed in registers).
* x86-64 ABI fixes.James Lyon2013-04-199-75/+334
| | | | | | | | | abitest now passes; however test1-3 fail in init_test. All other tests pass. I need to re-test Win32 and Linux-x86. I've added a dummy implementation of gfunc_sret to c67-gen.c so it should now compile, and I think it should behave as before I created gfunc_sret.
* Added some additional tests to abitest.cJames Lyon2013-04-181-13/+51
| | | | This is just to ensure that I haven't (and don't) really mess anything up.
* Tests in abitest.c now work on Win32.James Lyon2013-04-187-66/+173
| | | | | | | I expect that Linux-x86 is probably fine. All other architectures except ARM are definitely broken since I haven't yet implemented gfunc_sret for these, although replicating the current behaviour should be straightforward.
* Added ABI compatibility tests with native compiler using libtcc.James Lyon2013-04-173-1/+91
| | | | | | | | | | Only one test so far, which fails on Windows (with MinGW as the native compiler - I've tested the MinGW output against MSVC and it appears the two are compatible). I've also had to modify tcc.h so that tcc_set_lib_path can point to the directory containing libtcc1.a on Windows to make the libtcc dependent tests work. I'm not sure this is the right way to fix this problem.
