* | tests2: cleanupgrischka2014-04-075-32/+26
| | | | | | | | | | | | | | | | | | - remove -norunsrc switch Meaning and usage (-run -norun...???) look sort of screwed. Also general usefulness is unclear, so it was actually to support exactly one (not even very interesting) test This partially reverts e31579b0769e1f9c0947d12e83316d1149307b1a
* | win32: libtcc1.a needs to be built with tccgrischka2014-04-072-5/+8
| | | | | | | | | | gcc/mingw produces msvc compatible pecoff objects, tcc only knows ELF.
* | stdbool.h: Make conformant to ISOC99Michael Matz2014-04-071-0/+1
| | | | | | | | | | | | For conformance to ISO C the stdbool.h header has to provide the macro __bool_true_false_are_defined (defined to 1). Yep, that name is really in the standard.
* | Declare wint_t in <stddef.h> when neededMichael Matz2014-04-072-0/+24
| | | | | | | | | | Some old glibcs <wctype.h> require <stddef.h> to provide wint_t, accomodate them.
* | win32: warn people about using undeclared WINAPI functionsgrischka2014-04-061-4/+10
| | | | | | | | | | | | | | | | | | | | | | *** UNCONDITIONALLY *** Esp. sihce tinycc winapi headers are not as complete as people might expect this can otherwise lead to obscure problems that are difficult to debug. (Originally 'warn_implicit_function_declaration' was set to 1 always for windows but someone must have deleted that line)
* | ELF: Remove traces of old RUNTIME_PLTGOT codeMichael Matz2014-04-063-82/+1
| | | | | | | | | | The last users of it went away, no use in keeping this code.
* | arm: Use proper PLT/GOT for -run.Michael Matz2014-04-062-10/+54
| | | | | | | | | | | | | | | | | | | | | | Same as with x86_64, disable the runtime_plt_and_got hack for -run on arm as well. For that we need to handle several relocations as (potentially) generating PLT slots as well. Tested with mpfr-3.1.2 and gawk (both using --disable-shared), there are two resp. five pre-existing problems, so no regressions. This also works toward enabling real shared libs for arm, but it's not there yet.
* | x86_64: Create proper PLT and GOT also for -runMichael Matz2014-04-063-17/+24
| | | | | | | | | | | | This makes us use the normal PLT/GOT codepaths also for -run, which formerly used an on-the-side blob for the jump tables. For x86_64 only for now, arm coming up.
* | arm: Provide alloca()Michael Matz2014-04-053-4/+15
| | | | | | | | | | | | 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.
* | Git should ignore tests2 executables.Michael Matz2014-04-051-0/+1
| |
* | tests2: Build executables as wellMichael Matz2014-04-051-1/+6
| | | | | | | | | | The individual tests in tests2 are checked only with -run. Build (and check) executables as well, to test also building executables.
* | arm: Handle R_ARM_NONE relocsMichael Matz2014-04-041-0/+4
| | | | | | | | | | | | | | These relocations are used to express a dependency on a certain symbol (e.g. for EABIs exception handling to the __aeabi_unwind_cpp_pr{0,1,2} routines). Just ignore them in reloc processing.
* | tccgen: x86_64: fix garbage in the SValue upper bitsgrischka2014-04-043-70/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was going wrong (case TOK_LAND in unary: computed labels) - vset(&s->type, VT_CONST | VT_SYM, 0); - vtop->sym = s; This does the right thing and is shorter: + vpushsym(&s->type, s); Test case was: int main(int argc, char **argv) { int x; static void *label_return = &&lbl_return; printf("label_return = %p\n", label_return); goto *label_return; //<<<<< here segfault on linux X86_64 without the memset on vset printf("unreachable\n"); lbl_return: return 0; } Also:: - Rename "void* CValue.ptr" to more usable "addr_t ptr_offset" and start to use it in obvious cases. - use __attribute__ ((noreturn)) only with gnu compiler - Revert CValue memsets ("After several days searching ...") commit 4bc83ac3933efa565ae3326b55fcd711b63c073d Doesn't mean that the vsetX/vpush thingy isn't brittle and there still might be bugs as to differences in how the CValue union was set and is then interpreted later on. However the big memset hammer was just too slow (-3% overall).
* | run: Always create .got relocsMichael Matz2014-04-041-0/+7
| | | | | | | | | | | | | | When output is memory we applied the correct GOT offset for certain relocations (e.g. _GOT32), but we forgot to actually fill the got entries with the final symbol values, so unconditionally create relocs against .got as well.
* | ELF: Make first PT_LOAD cover headersMichael Matz2014-04-031-5/+10
| | | | | | | | | | | | | | | | This makes it so that the first PT_LOAD segment covers ELF and program header and .interp (contained in the same page anyway, right before the start of the first loaded section). binutils strip creates invalid output otherwise (which strictly is a binutils bug, but let's be nice anyway).
* | x86-64: Use correct ELF valuesMichael Matz2014-04-031-2/+2
| | | | | | | | | | The x86-64 uses different segment alignment (2MB) and a different start address.
* | 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.
* | Allow local redefinition of enumeratorThomas Preud'homme2014-03-314-2/+17

* | x86-64: shared libs improvementMichael Matz2014-03-312-26/+46
| | | | | | | | | | | | | | | | | | | | This correctly resolves local references to global functions from shared libs to their PLT slot (instead of directly to the target symbol), so that interposition works. This is still not 100% conforming (executables don't export symbols that are also defined in linked shared libs, as they must), but normal shared lib situations work.
* | x86-64: Add basic shared lib supportMichael Matz2014-03-312-37/+41
| | | | | | | | Initial support for shared libraries on x86-64.
* | Add __attribute__ ((noreturn)) to tcc_error and expect functions.mingodad2014-03-301-2/+2
| | | | | | | | This make use of static analysis tools like scan-build report less false positives.
* | Add tests for previous fixesThomas Preud'homme2014-03-3011-1/+30
| | | | | | | | | | | | | | | | | | Add tests for the fixes made in commits 76cb1144ef91924c53c57ea71e6f67ce73ce1cc6, a465b7f58fdea15caa1bfb81ff5e985c94c4df4a, 0f522fb32a635dafce30f3ce3ff2cb15bcec809e, 82969f045c99b4d1ef833de35117c17b326b46c0 and 673befd2d7745a90c1c4fcb6d2f0e266c04f8c97.

* | x86_64: pass va_list as pointerDaniel Glöckner2014-03-301-4/+4
| | | | | | | | | | | | The ABI requires that va_list is passed as a pointer although its contents is a kept in a structure. Therefore make it a single element array.
* | tccpp: reorder some tokensgrischka2014-03-292-21/+56

* | ARM: Fix passing arrays to varadic functionsDaniel Glöckner2014-03-291-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TinyCC miscompiled void g(int,...); void f(void) { char b[4000]; g(1, 2, 3, 4, b); } in two ways: 1. It didn't align the stack to 8 bytes before the call 2. It added sizeof(b) to the stack pointer after the call

* | Fix again GOT32 + PLT32 reloc commitThomas Preud'homme2014-03-291-4/+3
| | | | | | | | | | Fix commit aa561d70119accb59a17f10f9ba69076fb0ab516 by setting has_plt_entry once the plt has been created, not before.
* | Create bcheck region for argv and arge argumentThomas Preud'homme2014-03-293-0/+23
| | | | | | | | | | | | | | | | | | | | | | 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 get_tok_str support NULL as second param.Thomas Preud'homme2014-03-291-0/+6
| | | | | | | | | | | | | | As was pointed out on tinycc-devel, many uses of get_tok_str gives as second parameter the value NULL. However, that pointer was unconditionally dereferenced in get_tok_ptr. This commit explicitely add support for thas case.

* | Simplify and fix GOT32 + PLT32 reloc commitThomas Preud'homme2014-03-262-3/+3
| | | | | | | | | | | | | | | | Introduce a new attribute to check the existence of a PLT entry for a given symbol has the presence of an entry for that symbol in the dynsym section is not proof that a PLT entry exists. This fixes commit dc8ea93b13faefb565fb937f8b8c08c40c063549.

* | Support GOT32 and PLT32 reloc for same symbolThomas Preud'homme2014-03-251-11/+31
| | | | | | | | | | | | | | Some symbol (such as __gmon_start__ but this one does not matter to tcc) can have both a R_386_GOT32 and R_386_PLT32 relocation. It is thus not enough to test if a GOT reloc was already done when deciding whether to return early from put_got_entry.

* | Warn about soft float ABI not being supportedThomas Preud'homme2014-03-251-0/+3
| | | | | | | | | | | | For ARM target, tcc uses the soft float ABI when not asked to use hard float ABI. This means machine without a VFP co-processor generate code that they cannot run. This commit add a warning for such cases.
