* Add a new isSignWrappedSet() method to ConstantRange.Nick Lewycky2010-09-063-7/+42
| | | | | | | | | | Fix zeroExtend and signExtend to support empty sets, and to return the smallest possible result set which contains the extension of each element in their inputs. For example zext i8 [100, 10) to i16 is now [0, 256), not i16 [100, 10) which contains 63446 members. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113187 91177308-0d34-0410-b5e6-96231b3b80d8

* generalize my previous operand loc info hack. If the same operandChris Lattner2010-09-061-7/+9
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113183 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | 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

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

* now that the opcode is trivially exposed, start matching instructionsChris Lattner2010-09-061-6/+22

* special case the mnemonic operand of the instruction in the Chris Lattner2010-09-061-8/+29
| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113169 91177308-0d34-0410-b5e6-96231b3b80d8

* have tblgen detect when an instruction would have matched, butChris Lattner2010-09-062-40/+55
| | | | | | | | | | | | | | 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

Duplicating them into the end of the loop and the preheader means that we got a phi node in the header of the loop, which prevented LICM from hoisting them. GVN would usually come around later and merge the duplicated instructions so we'd get reasonable output... except that anything dependent on the shoulda-been-hoisted value can't be hoisted.
