| | | | This was fixed by 1c2dfa1 on 2015-11-21.
* i386: Add support for new psABI relocationThomas Preud'homme2015-12-272-3/+11
| | | | | | | R_386_GOT32X can occur in object files assembled by new binutils, and in particular do appear in glibc startup code (crt*.o). This patch is modeled after the x86_64 one, handling the new relocation in the same trivial way.
* x86-64: fix shared libsMichael Matz2015-12-171-2/+4
| | | | | | | | | | | | | | The introduction of read32le everywhere created a subtle issue, going from x = *(int*)p; to x = read32le(p); is not equivalent if x is a larger than 32bit quantity, like an address on x86_64, because read32le returns an unsigned int. The first sign extends, the latter zero extends. This broke shared library creation for gawk. It's enough to amend the case of the above situation, cases like "write32le(p, read32le(p) +- something)" are okay, no extensions happen or matter.
* x86-64: Define symbol constant for new relocsMichael Matz2015-12-172-7/+13
| | | | | | Whoops, we have our own <elf.h> copy, so I can just as well add the symbol defines for the relocs instead of hard-coding numbers in tccelf.c.
* x86-64: Add support for new psABI relocationsMichael Matz2015-12-171-4/+10
| | | | | | | | | R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX can occur in object files comiled by new binutils. They are not dynamic relocations, so normally wouldn't be a problem for tcc (one doesn't normally mix object files created by different compiler/binutils, static archives are so out :)). If it weren't for the glibc startup code, crt*.o, of course. They now do contain such relocs --> boom. Handle them in the trivial way.
* Fixed a dependency (error with make -j8).Vincent Lefevre2015-12-151-1/+1

* Change the way struct CStrings are handled.Edmund Grimley Evans2015-11-266-66/+67
| | | | | | | | | A CString used to be copied into a token string, which is an int array. On a 64-bit architecture the pointers were misaligned, so ASan gave lots of warnings. On a 64-bit architecture that required memory accesses to be correctly aligned it would not work at all. The CString is now included in CValue instead.

* tccgen.c: Give error if statement expression found when const wanted.Edmund Grimley Evans2015-11-261-6/+2
| | | | | | | | | | | | | | | | Some test cases: #define SE ({ switch (0) { } 0; }) // Should give error: int x = SE; void f(void) { static int x = SE; } void f(void) { enum e { a = SE }; } void f(void) { switch (0) { case SE: break; } } // Correct: int f(void) { return SE; } int f(void) { return sizeof(SE); }
* tcc.h: Change order of built-in include paths: put TCC's own dir first.Edmund Grimley Evans2015-11-231-3/+3
| | | | | There may be compiler-specific header files that should override system headers. See TCC's include paths by running "tcc -vv".
* tccgen.c: Try to make sizeof(!x) work.Edmund Grimley Evans2015-11-223-3/+4
| | | | tests/tests2/27_sizeof.*: Add test.

* Bug fix for commit 553242c18a2387fb896df66eb9b5a502f0e87ff0.Edmund Grimley Evans2015-11-202-10/+14
| | | | | | In gtst, vtop->c.i is not usually zero, but it is when compiling: int f(void) { return 1 && 1 ? 1 : 1; }
* tccpp: allow .. in token streamgrischka2015-11-201-4/+7
| | | | | | | | | | for gas comments lonely on a line such as # .. more stuff where tcc would try to parse .. as a preprocessor directive See also: 0b3612631f49ba0c008635aaa46ecf8be2eefcf7
* tccpp: cleanup #include_nextgrischka2015-11-203-127/+46
| | | | | | | | | | | | | | | | tcc_normalize_inc_dirs: normally no problem to be absolutly gcc compatible as long as it can be done the tiny way. This reverts to the state before recent related commits and reimplements a (small) part of it to fix the reported problem. Also: Revert "parsing "..." sequence" c3975cf27c792d493e76a2058a1eaf588324053e && p[1] == '.' is not a reliable way to lookahead
* tccgen: asm_label cleanupgrischka2015-11-204-42/+42
| | | | | | | - avoid memory allocation by using its (int) token number - avoid additional function parameter by using Attribute Also: fix some strange looking error messages
* tccgen.c: Recognise constant expressions with conditional operator.Edmund Grimley Evans2015-11-202-10/+21
| | | | tests/tests2/78_vla_label.c: Check that int a[1 ? 1 : 1] is not a VLA.
* tccgen.c: In parse_btype, handle typedef types with added type qualifiers.Edmund Grimley Evans2015-11-191-1/+11
| | | | | | | | | | | | | | | | | | In a case like typedef int T[1]; const T x; we must make a copy of the typedef type so that we can add the type qualifiers to it. The following code used to give error: incompatible types for redefinition of 'f' typedef int T[1]; void f(const int [1]); void f(const T);
* tccgen.c: Improvements to type_to_str (only used for error messages).Edmund Grimley Evans2015-11-191-0/+9
| | | | | 1. Handle array types. 2. Print the type qualifiers of pointers.
* Trivial changes to avoid some compiler warnings.Edmund Grimley Evans2015-11-195-9/+12

* Replace pointer casts with calls to (read|write)(16|32|64)le.Edmund Grimley Evans2015-11-195-170/+185
| | | | | This stops UBSan from giving runtime misaligned address errors and might eventually allow building on a non-little-endian host.
