* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | crashing, I found the problem it was because CValue stack variables have rubish as it inital values and assigning to a member that is smaller than the big union item and trying to recover it later as a different member gives bak garbage. ST_FUNC void vset(TCCState* tcc_state, CType *type, int r, int v) { CValue cval; memset(&cval, 0, sizeof(CValue)); cval.i = v; //,<<<<<<<<<<< here is the main bug that mix with garbage vsetc(tcc_state, type, r, &cval); } /* store a value or an expression directly in global data or in local array */ static void init_putv(TCCState* tcc_state, CType *type, Section *sec, unsigned long c, int v, int expr_type) { ... case VT_PTR: if (tcc_state->tccgen_vtop->r & VT_SYM) { greloc(tcc_state, sec, tcc_state->tccgen_vtop->sym, c, R_DATA_PTR); } //<<< on the next line is where we try to get the assigned value to cvalue.i as cvalue.ull *(addr_t *)ptr |= (tcc_state->tccgen_vtop->c.ull & bit_mask) << bit_pos; break; Also this patch makes vla tests pass on linux 32 bits
* 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.
* Always link libtcc1.a in (useful for va_* on x86)Thomas Preud'homme2014-03-252-6/+3
| | | | On x86 tcc call to function in libtcc1.a to implement va_* functions.
* Add test for previous commitThomas Preud'homme2014-03-255-4/+10
| | | | | * Adapt tests2 Makefile to support testing tcc error reporting * Add test for previous commit
* 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.

* Make parse_btype only accept one basic typeThomas Preud'homme2014-03-241-8/+15
| | | | | This makes int char c; and struct {} int c; generate an error. Thanks Mobi Phil for reporting.
* Fix relocation of __bound_initThomas Preud'homme2014-03-171-2/+8
| | | | | | | When bound check is enabled, tcc tries to relocate a call to __bound_init in _init. This means that relocation (in tcc_add_bcheck) must be done after libtcc1.a (which countains __bound_init) is loaded but before crtn.o is loaded as this finalize _init.
* Fix __clear_cache implementationThomas Preud'homme2014-03-111-1/+2

* 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.

* Call fill_got_entry unconditionallyThomas Preud'homme2014-02-101-2/+0
| | | | | | Call fill_got_entry unconditionally from fill_got so as to avoid warnings on !x86-64 architectures. This can be done since this code path is only followed by x86-64 architecture anyway.

* Def signedness != signed != unsigned for charThomas Preud'homme2014-02-064-15/+26
| | | | | | | | When checking for exact compatibility between types (such as in __builtin_types_compatible_p) consider the case of default signedness to be incompatible with both of the explicit signedness for char. That is, char is incompatible with signed char *and* unsigned char, no matter what the default signedness for char is.

* Fix and extend *FCAST test in tcctest.cThomas Preud'homme2014-02-051-5/+8
| | | | | | | Result of float to unsigned integer conversion is undefined if float is negative. This commit take the absolute value of the float before doing the conversion to unsigned integer and add more float to integer conversion test.

* switch last 2 params of TOK_memset on ARMThomas Preud'homme2014-02-031-0/+5

* Switch float abi to softfp for int <--> float convThomas Preud'homme2014-02-021-17/+9
| | | | | | | This improves commit 5cbe03b9c47e676e045b4978c384087433bd6042 by avoiding a double transfer when the default float ABI is already softfp. It's also more clean by expliciting that the ABI is simply changed for runtime ABI functions.
