* assemble.c: only warn for an absolute address on pass 2nasm-2.12.xxH. Peter Anvin2017-02-201-2/+2
| | | | | | | | | A forward symbol may appear absolute in pass 1, so defer this warning to pass 2. This addresses BR 3392361. Note: this fix is already in the master branch. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

* assemble: print a warning on a forward reference in RESxH. Peter Anvin2016-10-031-0/+3
| | | | | | | Print a warning on a forward reference in RESx. This really should have been a critical expression, and a forward reference should have been an error, but it wasn't implemented that way and as such we can't just randomly break people's code, even if it is dangerous.
* Correct /is4 encoding for EVEX instructionsH. Peter Anvin2016-09-201-18/+19
| | | | | | | | For EVEX instructions, /is4 can contain a fifth register bit, encoded in bit 3 of the imm8. Properly generate this case, and simplifiy the /is4 generation code somewhat. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* insns.dat: Enable contracted forms for additional instructionsHenrik Gramner2016-08-251-516/+516
| | | | | | | | | | | | | | | | | | | Improve consistency by allowing contracted forms for EVEX-encoded instructions when it's allowed for similar VEX-encoded instructions. Previously the behavior would change depending on the vector size or the register number which could be somewhat confusing: vaddps xmm0, xmm1 ; ok vaddps ymm0, ymm1 ; ok vaddps zmm0, zmm1 ; error vaddps xmm0, xmm16 ; error Also allow contracted forms for a few additional older AVX instructions where it makes sense.

* codeview: Fix ill-formed "S_COMPILE2" record.Fabian Giesen2016-07-271-8/+16
| | | | | | | | | | | | | | write_symbolinfo_properties didn't match the S_COMPILE2 record it's supposed to be writing (the "compiler version" string was emitted starting in the final "version" field); fix that. Write version 8.0.50727; the Windows App Certification Kit (WACK) checks compiler versions as given in app debug info and complains when the toolchain is too old. 8.0.50727 is the lowest permitted "MASM" version for WACK to be happy, so that's what we write.

* Add explicit void parameter to newmembuf() function declaration.bcallah@devio.us2016-07-141-1/+1
| | | | | | | | | | | In rdoff/rdoff.c, the function declaration for newmembuf is written: static memorybuf *newmembuf() The attached diff adds an explicit void parameter. It seems like it would be nicer with an explicit void parameter especially since the -Werror build options seem to want to find such things. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* compiler.h: always undefine __STRICT_ANSI__ for gccH. Peter Anvin2016-07-141-2/+5
| | | | | | | | | | | | It is not just DJGPP which has broken header files if __STRICT_ANSI__ is defined. Cygwin has also been confirmed to have problems. It would be somewhat different if configure didn't still detect those functions. Undefine __STRICT_ANSI__ for all gcc platforms. If this breaks then, well, we'll have to really narrow down the problems. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

* outobj.c: Fix for RIP relative addressing relocation.knut st. osmundsen2016-06-031-2/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 16-bit and 32-bit x86 code, the size and realsize() always matches as only jumps, calls and loops uses PC relative addressing and the address isn't followed by any other opcode bytes. In 64-bit mode there is RIP relative addressing which means the fixup location can be followed by an immediate value, meaning that size > realsize(). When the CPU is calculating the effective address, it takes the RIP at the end of the instruction and adds the fixed up relative address value to it. The linker's point of reference is the end of the fixup location (which is the end of the instruction for Jcc, CALL, LOOP[cc]). It is calculating distance between the target symbol and the end of the fixup location, and add this to the displacement value we are calculating here and storing at the fixup location. To get the right effect, we need to _reduce_ the displacement value by the number of bytes following the fixup. Example: data at address 0x100; REL4ADR at 0x050, 4 byte immediate, end of fixup at 0x054, end of instruction at 0x058. => size = 8. => realsize() -> 4 => CPU needs a value of: 0x100 - 0x058 = 0x0a8 => linker/loader will add: 0x100 - 0x054 = 0x0ac => We must add an addend of -4. => realsize() - size = -4. The code used to do size - realsize() at least since v0.90, probably because it wasn't needed... Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | There is no reason why the warning-generating ilog2 has to be only the floor variant. However, I am pretty sure we can simply implement the ilog2cw() as a macro only; we can always fix that if that turns out to be incorrect. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
