2004-10-15Instruction select globals with offsets better. For example, on this testChris Lattner
case: int C[100]; int foo() { return C[4]; } We now codegen: foo: mov %EAX, DWORD PTR [C + 16] ret instead of: foo: mov %EAX, OFFSET C mov %EAX, DWORD PTR [%EAX + 16] ret Other impressive features may be coming later. This patch is contributed by Jeff Cohen! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17011 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-15Give the X86 asm printer the ability to print out addressing modes that haveChris Lattner
constant displacements from global variables. Patch by Jeff Cohen! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17009 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-15Allow X86 addressing modes to represent globals with offsets. Patch contributedChris Lattner
by Jeff Cohen! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17008 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-15Allow machine operands to represent global variables with offsets. This isChris Lattner
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
2004-10-15This patch fixes the nasty bug that caused 175.vpr to fail for X86 last night.Chris Lattner
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

2004-10-15Better codegen of binary integer ops with 32 bit immediate operands.Nate Begeman
This transformation fires a few dozen times across the testsuite.
