For instructions that can be encoded either in VEX or EVEX,
{evex} forces nasm to encode in EVEX.

BND prefix is used for adding bounds checking protection
across flow control changes such as call, ret, jmp and jcc calls.

AVX-512 introduced new syntax using braces for decorators.
Opmask, broadcat, rounding control use this new syntax.

Add general support in the function parser for "integer functions"
(actually implemented as special unary operators, then wrapped in
macros) and implement a family of integer logarithms. The only
difference is the behavior on a non-power-of-two argument:
ilog2[e] -- throw an error
ilog2w -- throw a warning
ilog2f -- round down to power of 2
ilog2c -- round up to power of 2
This is useful for back-converting from masks to bit values.

Add support for bigendian UTF-16 and UTF-32, and (for symmetry) add
explicitly littleendian operators.

This implements the mechanism for XACQUIRE/XRELEASE. It does not
include the necessary annotations in insns.dat.

WAIT is technically an instruction, but from an assembler standpoint
it behaves as if it had been a prefix. In particular, it has to be
ordered *before* any real hardware prefixes.
|
|
Implement __utf16__() and __utf32__() for the DB family of
pseudo-instructions. Not yet implemented for evaluation context.
|
|
Add the DY instruction, YWORD keyword, and an SY marker for
instruction sizes. Add a few more AVX sample instructions.
|
|
Use a 32-bit limb size ("like a digit, but bigger") for floating-point
conversion. This cuts the number of multiplications per constant by a
factor of four.
This means supporting fractional-limb-sized numbers, so while we're at
it, add support for 8-bit floating point numbers (apparently used in
graphics and in audio compression applications.)
|
|
Revamp the address- and prefix-handling code to make more sense in
64-bit mode. We are now a lot closer to where we want to be, but
we're not quite there yet.
ndisasm may very well have problems, or give counterintuitive output.
However, checking it in so we can make forward progress.

Add special operators to allow the use of floating-point constants in
contexts other than DW/DD/DQ/DT/DO.
As part of this checkin, make MAX_KEYWORD generated by tokhash.pl,
since it knows what all the keywords are so it can tell which one is
the longest.
|
|
Support generating NaNs and infinities as part of floating-point
constants.
|
|
Implement oword, reso, do, as well as the SO flag to instructions. No
instructions are actually flagged with SO yet, but this allows us to
specify 128-bit sizes in instruction patterns.

Order of token arguments was reversed, but tokens.dat wasn't updated
accordingly. Fix.
|
|
Finish the perfect hash tokenizer, and actually enable it.
Move stdscan() et al to a separate file, since it's not needed in any
of the clients of nasmlib other than nasm itself.
Run make alldeps.
