svn path=/branches/multiarch/; revision=1964
Peter Johnson [Wed, 19 Sep 2007 07:47:10 +0000 (07:47 -0000)]
Support NASM's upcoming RIP-relative syntax, with a few differences.
This adds a "default" directive that takes either "rel" or "abs". This
sets whether the default mode for simple displacements is RIP-relative (rel)
or not (abs). The default without a directive is "abs".
Also added is corresponding "rel" and "abs" effective address modifiers
to override whatever default is set:
[rel label] is RIP-relative
[abs label] is not.
In default rel mode, [label] defaults to the former, in default abs mode,
the latter. Also, segment overrides (note difference from NASM below) are
abs regardless of mode, unless explicitly overridden with rel:
[fs:label] is always abs
[rel fs:label] is always rel
However, we have a number of differences from NASM in this handling due to
what I feel to be yasm's more sane handling of [dword ...] and [qword ...].
In yasm, these set the displacement size, rather than the address size; the
latter is set using a a32/a64 prefix. I feel this is more sane as in 64-bit
mode the two can be different in the MovOffs (A0/A1 mov *ax) case.
Also, yasm disables default-rel mode if any segment register is used, not
just FS or GS as NASM currently does.
See modules/arch/x86/tests/riprel1.asm and
modules/arch/x86/tests/riprel2.asm for examples, as well as my recent
posting to the nasm-devel mailing list on SF.

Fix use-after-free in linemap_poke. The first yasm_linemap_set call can
realloc linemap->map->vector, invalidating the mapping pointer.

Fix #102: Permit non-standard macho section names.
Two forms are legal ({} are replaceables):
SECTION {segname} {sectname}
SECTION {sectname} segname={segname}
Also,
SECTION {sectname}
where sectname is unrecognized is also legal, defaults segname to __TEXT,
and generates a warning.

Clean up directive handling. This standardizes error/warning messages and
makes value/parameters more well-defined and flexible enough to handle
string parameters. Value/parameters would now be better called name/values,
but avoid changing the name for now.

Move absolute section handling into NASM parser, removing all traces of it
from libyasm core. Now absolute sections are tracked locally to the parser
and the parser generates EQUs directly for labels in absolute sections.
Fixes #106 and #103.

Fix handling of SVM (AMD Pacifica) instructions that take an implicit
rax/eax/ax operand. This operand actually selects the address size, so
make it a memory operand instead of a register operand (GAS follows this
approach as well). Enable SVM instructions in non-64-bit mode as well.
Now the following opcodes work as intended:
invlpga [rax/eax/ax], ecx
skinit [eax]
vmload/vmrun/vmsave [rax/eax/ax]

Fix bug relating to recognizing crc32 rax, bh as an error: the opersize=64
