2003-09-08Eliminate support for the llvm.unwind intrinisic, using the Unwind ↵Chris Lattner

2003-09-08Add support for the unwind instructionChris Lattner

2003-08-28Add support for the llvm.unwind intrinsic, which we codegen to just do an abortChris Lattner
until we implement unwinding. Add support for the invoke instruction, which codegens just like a call with a branch after it. The end effect of this change is that programs using the invoke instruction, but never unwinding, will work fine. Programs that unwind will abort until we get unwind support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8187 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-18Please, save your applause^H^H^H^H^H^H^H^Hflames for the end...Brian Gaeke
Avoid a fall-through in the (stubby) treatment of the longjmp intrinsic call which causes llc & lli to core-dump. Add a sort-of treatment of cast double to ulong. I am not really sure what a user should expect to see upon casting a negative FP value to unsigned long long. But with what is given here, I was able to write a program that could cast -123.456 to ulong and back and get -123.0, which seems like a step in the right direction. GCC seems to give you 0. I don't know if I'd consider that useful. These cases were coming up in GNU coreutils-5.0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7205 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-30Setjmp should always return zero if we don't implement longjmp. This avoidsChris Lattner

2003-06-05Special case simple binary operator X op CChris Lattner
This avoid generating a register to hold C, which in turn speeds up the register allocator by a lot: ~9% on 164.gzip and ~17% on 256.bzip2. This also speeds up other passes. This also speeds up execution of the program marginally, and makes the asm much easier to read. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6626 91177308-0d34-0410-b5e6-96231b3b80d8
