2004-11-04Thanks to sabre for pointing out that we were incorrectly codegen'ingNate Begeman
int test(int x) { return 32768 - x; } Fixed by teaching the function that checks a constant's validity to be used as an immediate argument about subtract-from instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17476 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-02Fix this function to not say that longs have 8-byte alignment on X86/PPC.Chris Lattner
This method is really a gross hack, but at least we can make it work on the targets we support right now. This bug fix stops a crash in a testcase reduced from 176.gcc git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17443 91177308-0d34-0410-b5e6-96231b3b80d8

function pointer equivalences. This fixes many problems, including a testcase reduced Prolangs-C++/objects. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17437 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-02Substantially cleanup/speedup the eq graphs pass by walking the callgraphChris Lattner
a DSGraph at a time instead of a function at a time. This is also more correct, though it doesn't seem to fix any programs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17435 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-01Do not compute the predecessor list for a block unless we need it.Chris Lattner
This speeds up simplifycfg on this program, from 44.87s to 0.29s (with a profiled build): #define CL0(a) case a: goto c; #define CL1(a) CL0(a##0) CL0(a##1) CL0(a##2) CL0(a##3) CL0(a##4) CL0(a##5) \ CL0(a##6) CL0(a##7) CL0(a##8) CL0(a##9) #define CL2(a) CL1(a##0) CL1(a##1) CL1(a##2) CL1(a##3) CL1(a##4) CL1(a##5) \ CL1(a##6) CL1(a##7) CL1(a##8) CL1(a##9) #define CL3(a) CL2(a##0) CL2(a##1) CL2(a##2) CL2(a##3) CL2(a##4) CL2(a##5) \ CL2(a##6) CL2(a##7) CL2(a##8) CL2(a##9) #define CL4(a) CL3(a##0) CL3(a##1) CL3(a##2) CL3(a##3) CL3(a##4) CL3(a##5) \ CL3(a##6) CL3(a##7) CL3(a##8) CL3(a##9) void f(); void a() { int b; c: switch (b) { CL4(1) } } This testcase is contrived to expose N^2 behavior, but this patch should speedup simplifycfg on any programs that use large switch statements. This testcase comes from GCC PR17895. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17389 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-31* Do not refer to ActualCallees in CBU, when we can do it locally.Chris Lattner
* *DO NOT* print CBU graphs when asked to print our own. This is just FREAKING confusing and misleading: it's better to not print anything. * Simplify and clean up some code * Add some more paranoia assertion checking code that I found to track down this bug: * Fix a nasty bug that was causing us to crash on Prolangs-C++/objects, where we were missing processing some graphs. This hunk is the bugfix: - if (!I->isExternal() && !FoldedGraphsMap.count(I)) + if (!I->isExternal() && !ValMap.count(I)) urg! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17386 91177308-0d34-0410-b5e6-96231b3b80d8
