For each instruction itinerary class, specify the number of micro-ops each
...
instruction in the class would be decoded to. Or zero if the number of
uOPs must be determined dynamically.
This will be used to determine the cost-effectiveness of predicating a
micro-coded instruction.

generalize my previous operand loc info hack. If the same operand
...
is busted for all variants, report it as the location. This allows
us to get the operand right for bugs like:
t.s:3:12: error: invalid operand for instruction
outb %al, %gs
^
Even though there are reg/imm and reg/reg forms of this instruction.
llvm-svn: 113183
2010-09-06 23:37:39 +00:00
339cc7bfef
in the case where an instruction only has one implementation
...
of a mneumonic, report operand errors with better location
info. For example, we now report:
t.s:6:14: error: invalid operand for instruction
cwtl $1
^
but we fail for common cases like:
t.s:11:4: error: invalid operand for instruction
addl $1, $1
^
because we don't know if this is supposed to be the reg/imm or imm/reg
form.
llvm-svn: 113178
2010-09-06 22:11:18 +00:00
628fbecf4f
Now that we know if we had a total fail on the instruction mnemonic,
...
give a more detailed error. Before:
t.s:11:4: error: unrecognized instruction
addl $1, $1
^
t.s:12:4: error: unrecognized instruction
f2efqefa $1
^
After:
t.s:11:4: error: invalid operand for instruction
addl $1, $1
^
t.s:12:4: error: invalid instruction mnemonic 'f2efqefa'
f2efqefa $1
^
This fixes rdar://8017912 - llvm-mc says "unrecognized instruction" when it means "invalid operands"

special case the mnemonic operand of the instruction in the

generated matcher, emiting it as a column in the MatchEntry
table instead of forcing it to go through classification and
everything else. Making it be classified caused tblgen to
produce a ton of one-off classes for each mneumonic. This
should reduce the size of the generated matcher significantly
while paving the way for future improvements.

have tblgen detect when an instruction would have matched, but
...
failed because a subtarget feature was not enabled. Use this to
remove a bunch of hacks from the X86AsmParser for rejecting things
like popfl in 64-bit mode. Previously these hacks weren't needed,
but were important to get a message better than "invalid instruction"
when used in the wrong mode.
This also fixes bugs where pushal would not be rejected correctly in
32-bit mode (just pusha).
