2004-12-13Get rid of getSizeOf, using ConstantExpr::getSizeOf instead.Chris Lattner
do not insert a prototype for malloc of: void* malloc(uint): on 64-bit u targets this is not correct. Instead of prototype it as void *malloc(...), and pass the correct intptr_t through the "...". Finally, fix Regression/CodeGen/SparcV9/2004-12-13-MallocCrash.ll, by not forming constantexpr casts from pointer to uint. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18908 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-30If we have something like this:Chris Lattner
if (x) { code ... } else { code ... } Turn it into: code if (x) { ... } else { ... } This reduces code size and in some common cases allows us to completely eliminate the conditional. This turns several if/then/else blocks in loops into straightline code in 179.art, turning the loops into single basic blocks (good for modsched even!). Maybe now brg will leave me alone ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18366 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

2004-10-18Fix a bug that occurs when the constant value is the result of an invoke. InChris Lattner
particular, invoke ret values are only live in the normal dest of the invoke not in the unwind dest. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17108 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-17When inserting PHI nodes, don't insert any phi nodes that are obviouslyChris Lattner
unneccesary. This allows us to delete several hundred phi nodes of the form PHI(x,x,x,undef) from 253.perlbmk and probably other programs as well. This implements Mem2Reg/UndefValuesMerge.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17098 91177308-0d34-0410-b5e6-96231b3b80d8

2004-09-19Remove a whole bunch of horrible hacky code that was used to promote allocasChris Lattner
whose addresses where used by trivial phi nodes and select instructions. This is now performed by the instcombine pass, which is more powerful, is much simpler, and is faster. This allows the deletion of a bunch of code, two FIXME's and two gotos. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16406 91177308-0d34-0410-b5e6-96231b3b80d8

2004-08-13If we are extracting a block that has multiple successors that are the sameChris Lattner
block (common in a switch), make sure to remove extra edges in successor blocks. This fixes CodeExtractor/2004-08-12-BlockExtractPHI.ll and should be pulled into LLVM 1.3 (though the regression test need not be, as that would require pulling in the LoopExtract.cpp changes). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15717 91177308-0d34-0410-b5e6-96231b3b80d8
