these cases seems to be a bug. If you get a linker error about ADDR32, it
means you aren't using RIP-relative instructions. Note this means to access
an array you need to do:
lea rax, [var wrt rip] ; generates RIP-relative insn and REL32 reloc
mov rcx, [rax+rbx] ; rbx is index
and not:
mov rcx, [var+rbx] ; generates ADDR32 reloc
At least when trying to build a DLL (the ADDR32 reloc fails the DLL link).
When building statically, ADDR32 should work okay and thus the latter form
can be used.
svn path=/trunk/yasm/; revision=1257
output better by generating relocs directly to the symbol being relocated
rather than to the section. Use a new coff_objfmt->win64 flag to
conditionalize this rather than just COFF_MACHINE_AMD64.
(coff_objfmt): New win64 flag.
(coff_objfmt_create, win32_objfmt_create, win64_objfmt_create): Initialize
flag.
(coff_objfmt_output): Turn on outputting all symbols in win64 mode so they
can be referenced by relocs. This isn't quite correct: we should only turn
on the symbols that are actually used by relocs, but having them there
doesn't hurt linking; it only exposes all of the internal symbol names.
With these changes, yasm output matches the new ML64 output except for a
very few cases:
- ML64 generates REL32 relocs when referencing objects in the same .text
section. I cannot see how this is necessary because call instructions
don't generate REL32 relocs! I currently do not plan on fixing this unless
it causes a problem.
- ML64 generates ADDR32 relocs instead of REL32 relocs when loading a
32-bit register with the address of an object. I will probably try to fix
this.
Extended test case for this a bit.

defining the mov forms for GAS. While I'm here, fix movq so it also
supports the 64-bit move registers (per Intel's spec, AMD has it under movd)
and copy the MMX/SSE2 versions of movq into mov so they're visible to the
GAS parser (and only the GAS parser).
Add a whole bunch of testcases to test movd and movq in both 32 bit and 64
bit modes for both GAS and NASM parsers.

instructions in Win64 to always be REL32 regardless of whether they're
RIP relative or not. I don't understand this behavior, but it matches how
ML64 generates relocs and unbreaks linking. The handling of this case must
be handled at a higher level somehow (either at the linker or the compiler).
Note that this REL32 generation behavior of ML64 happens only with the
latest version (VC8); the 2003 SP1 SDK ML64 doesn't do this.

This work is being done under contract with a company that has requested

* bc-int.h (yasm_effaddr): Add strong flag to indicate if the effective
address is definitely an effective address; GAS does not use [] to designate
effective addresses so it's otherwise impossible to tell the difference
between "expr(,1)" and just "expr" (important for the relative jump
instructions).
* bytecode.h (yasm_ea_set_strong): New function to set the strong flag.
* bytecode.c (yasm_ea_set_strong): Implementation.
* x86bc.c (yasm_x86__ea_create_reg): Initialize strong flag.
* arch.h (yasm_insn_operand): Add deref flag to indicate use of "*foo" in
GAS syntax.
* arch.c (yasm_operand_create_reg, yasm_operand_create_segreg)
(yasm_operand_create_mem, yasm_operand_create_imm): Set deref flag to 0.
* gas: GAS syntax lexer and parser. Not all directives are implemented yet
(some will require additional core bytecodes).
* elf-objfmt.c (elf_objfmt_section_switch): Add support for GAS-style
section flags.
* x86arch.h (yasm_arch_x86): Add parser setting.
* x86arch.c (x86_create): Check for gas parser and initialize setting.
* x86bc.c (yasm_x86__ea_create_expr): Transform val+RIP to val wrt RIP when
using the GAS parser (this is how GAS interprets "expr(%rip)").
* x86id.re: Too many changes to enumerate in detail. Add new modifiers for
GAS suffixes. Start using them in a couple instructions. Split check_id
into subfunctions (still one entry point at present).
(yasm_x86__finalize_insn): Support new modifiers, reverse operands, derefs.

(yasm_arch_create_error): New error typedef for yasm_arch_create() errors.
* lc3barch.c (lc3b_create): Update to match new yasm_arch_create().
* x86arch.c (x86_create): Likewise.
* yasm.c (main): Use new yasm_arch_create() and handle the two kinds of
errors it can now generate. Move parser creation up in the sequence so it
happens before the arch is created.
