2004-05-28Fix the big regression that has been killing the nightly tester these lastChris Lattner
few days. Apparently the old symbol table used to auto rename collisions in the type symbol table and the new one does not. It doesn't really make sense for the new one to do so, so we just make the client do it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13877 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-20Fix to make the CBE always emit comparisons inline. Hopefully this willChris Lattner
fix the really bad code we're getting on PPC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13609 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-20Fix a bug in outputting branches to constant PCs. Since the PC is supplied asBrian Gaeke
a full 64-bit address, it must be adjusted to fit in the branch instruction's immediate field. (This is only used in the reoptimizer, for now.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13608 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-13Two more improvements for null pointer handling: storing a null pointerChris Lattner
and passing a null pointer into a function. For this testcase: void %test(int** %X) { store int* null, int** %X call void %test(int** null) ret void } we now generate this: test: sub %ESP, 12 mov %EAX, DWORD PTR [%ESP + 16] mov DWORD PTR [%EAX], 0 mov DWORD PTR [%ESP], 0 call test add %ESP, 12 ret instead of this: test: sub %ESP, 12 mov %EAX, DWORD PTR [%ESP + 16] mov %ECX, 0 mov DWORD PTR [%EAX], %ECX mov %EAX, 0 mov DWORD PTR [%ESP], %EAX call test add %ESP, 12 ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13558 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-13Second half of my fixed-sized-alloca patch. This folds the LEA to computeChris Lattner
the alloca address into common operations like loads/stores. In a simple testcase like this (which is just designed to excersize the alloca A, nothing more): int %test(int %X, bool %C) { %A = alloca int store int %X, int* %A store int* %A, int** %G br bool %C, label %T, label %F T: call int %test(int 1, bool false) %V = load int* %A ret int %V F: call int %test(int 123, bool true) %V2 = load int* %A ret int %V2 } We now generate: test: sub %ESP, 12 mov %EAX, DWORD PTR [%ESP + 16] mov %CL, BYTE PTR [%ESP + 20] *** mov DWORD PTR [%ESP + 8], %EAX mov %EAX, OFFSET G lea %EDX, DWORD PTR [%ESP + 8] mov DWORD PTR [%EAX], %EDX test %CL, %CL je .LBB2 # PC rel: F .LBB1: # T mov DWORD PTR [%ESP], 1 mov DWORD PTR [%ESP + 4], 0 call test *** mov %EAX, DWORD PTR [%ESP + 8] add %ESP, 12 ret .LBB2: # F mov DWORD PTR [%ESP], 123 mov DWORD PTR [%ESP + 4], 1 call test *** mov %EAX, DWORD PTR [%ESP + 8] add %ESP, 12 ret Instead of: test: sub %ESP, 20 mov %EAX, DWORD PTR [%ESP + 24] mov %CL, BYTE PTR [%ESP + 28] *** lea %EDX, DWORD PTR [%ESP + 16] *** mov DWORD PTR [%EDX], %EAX mov %EAX, OFFSET G mov DWORD PTR [%EAX], %EDX test %CL, %CL *** mov DWORD PTR [%ESP + 12], %EDX je .LBB2 # PC rel: F .LBB1: # T mov DWORD PTR [%ESP], 1 mov %EAX, 0 mov DWORD PTR [%ESP + 4], %EAX call test *** mov %EAX, DWORD PTR [%ESP + 12] *** mov %EAX, DWORD PTR [%EAX] add %ESP, 20 ret .LBB2: # F mov DWORD PTR [%ESP], 123 mov %EAX, 1 mov DWORD PTR [%ESP + 4], %EAX call test *** mov %EAX, DWORD PTR [%ESP + 12] *** mov %EAX, DWORD PTR [%EAX] add %ESP, 20 ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13557 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-13Substantially improve code generation for address exposed locals (aka fixedChris Lattner
sized allocas in the entry block). Instead of generating code like this: entry: reg1024 = ESP+1234 ... (much later) *reg1024 = 17 Generate code that looks like this: entry: (no code generated) ... (much later) t = ESP+1234 *t = 17 The advantage being that we DRAMATICALLY reduce the register pressure for these silly temporaries (they were all being spilled to the stack, resulting in very silly code). This is actually a manual implementation of rematerialization :) I have a patch to fold the alloca address computation into loads & stores, which will make this much better still, but just getting this right took way too much time and I'm sleepy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13554 91177308-0d34-0410-b5e6-96231b3b80d8
