2004-05-14Clean up this pass somewhat:Brian Gaeke
Add better comments, including a better head-of-file comment. Prune #includes. Fix a FIXME that Chris put here by using doInitialization(). Use DEBUG() to print out debug msgs. Give names to basic blocks inserted by this pass. Expand tabs. Use InsertProfilingInitCall() from ProfilingUtils to insert the initialize call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13581 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-13Fix a nasty bug that caused us to unroll EXTREMELY large loops due to overflowChris Lattner
in the size calculation. This is not something you want to see: Loop Unroll: F[main] Loop %no_exit Loop Size = 2 Trip Count = 2147483648 - UNROLLING! The problem was that 2*2147483648 == 0. Now we get: Loop Unroll: F[main] Loop %no_exit Loop Size = 2 Trip Count = 2147483648 - TOO LARGE: 4294967296>100 Thanks to some anonymous person playing with the demo page that repeatedly caused zion to go into swapping land. That's one way to ensure you'll get a quick bugfix. :) Testcase here: Transforms/LoopUnroll/2004-05-13-DontUnrollTooMuch.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13564 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

2004-05-12Fix a really nasty bug from my changes on Monday to PHIElim. These changesChris Lattner
broke obsequi and a lot of other things. It all boiled down to MBB being overloaded in an inner scope and me confusing it with the one in the outer scope. Ugh! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13517 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-12Add non-const MachineBasicBlock::getParent() accessor method.Brian Gaeke
MBBs start out as #-1. When a MBB is added to a MachineFunction, it gets the next available unique MBB number. If it is removed from a MachineFunction, it goes back to being #-1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13514 91177308-0d34-0410-b5e6-96231b3b80d8
