2010-09-06"sldt <mem>" is ambiguous in 64-bit mode, but shouldChris Lattner
always be disambiguated as sldtw. sldtw and sldtq with a mem operands have the same effect, but sldtw is more compact. Force it to sldtw, resolving rdar://8017530 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113186 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-06fix the operand constraints of the immediate form of in/out,Chris Lattner
allowing unsigned 8-bit operands. This fixes rdar://8208481 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113182 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-06in the case where an instruction only has one implementationChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113178 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-06Now that we know if we had a total fail on the instruction mnemonic, Chris Lattner
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" git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113176 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-06simplify the hacks around jrcxz.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113167 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-06have tblgen detect when an instruction would have matched, butChris Lattner
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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113166 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-05remove some dead code. t2addrmode_imm8s4 is never used in a Chris Lattner
pattern, so there is no need to define a matching function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113122 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-05implement rdar://6653118 - fastisel should fold loads where possible.Chris Lattner
Since mem2reg isn't run at -O0, we get a ton of reloads from the stack, for example, before, this code: int foo(int x, int y, int z) { return x+y+z; } used to compile into: _foo: ## @foo subq $12, %rsp movl %edi, 8(%rsp) movl %esi, 4(%rsp) movl %edx, (%rsp) movl 8(%rsp), %edx movl 4(%rsp), %esi addl %edx, %esi movl (%rsp), %edx addl %esi, %edx movl %edx, %eax addq $12, %rsp ret Now we produce: _foo: ## @foo subq $12, %rsp movl %edi, 8(%rsp) movl %esi, 4(%rsp) movl %edx, (%rsp) movl 8(%rsp), %edx addl 4(%rsp), %edx ## Folded load addl (%rsp), %edx ## Folded load movl %edx, %eax addq $12, %rsp ret Fewer instructions and less register use = faster compiles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113102 91177308-0d34-0410-b5e6-96231b3b80d8
