* Allow machine operands to represent global variables with offsets. This isChris Lattner2004-10-151-5/+9
| | | | | | | | | | | | | | | | | | useful when you have a reference like: int A[100]; void foo() { A[10] = 1; } In this case, &A[10] is a single constant and should be treated as such. Only MO_GlobalAddress and MO_ExternalSymbol are allowed to use this field, no other operand type is. This is another fine patch contributed by Jeff Cohen!! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17007 91177308-0d34-0410-b5e6-96231b3b80d8
* This patch fixes the nasty bug that caused 175.vpr to fail for X86 last night.Chris Lattner2004-10-151-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The problem occurred when trying to reload this instruction: MOV32mr %reg2326, 8, %reg2297, 4, %reg2295 The value of reg2326 was available in EBX, so it was reused from there, instead of reloading it into EDX. The value of reg2297 was available in EDX, so it was reused from there, instead of reloading it into EDI. The value of reg2295 was not available, so we tried reloading it into EBX, its assigned register. However, we checked and saw that we already reloaded something into EBX, so we chose what reg2326 was assigned to (EDX) and reloaded into that register instead. Unfortunately EDX had already been used by reg2297, so reloading into EDX clobbered the value used by the reg2326 operand, breaking the program. The fix for this is to check that the newly picked register is ok. In this case we now find that EDX is already used and try using EDI, which succeeds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17006 91177308-0d34-0410-b5e6-96231b3b80d8
