2004-02-14The prologue/epilogue related method calls have no reason to return a value,Chris Lattner
make them return void. This allows us to avoid some costly MBB.size() calls git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11448 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-14A target that doesn't support these intrinsics will still meet spec (theChris Lattner
intrinsic will always produce zero), but it will behave unexpectedly, so warn like GCC does. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11444 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11433 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-14Use std::numeric_limits<float>::infinity() instead ofAlkis Evlogimenos
std::numeric_limits<float>::max() for weighting preallocated intervals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11427 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-14Use intrinsic lowering like the rest of the backends. Get rid of crufty hackyChris Lattner
code that worked around problems in the mangler git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11426 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-14Fix the logic in the name mangler. If there are two symbols named 'X', and oneChris Lattner
is external, make sure to mangle the *internal* one, not external one git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11424 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13There is no need to emit a shift if the size is constant, which is commonChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11420 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11415 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13Convert the C backend into a target, for use with LLC. This allows us to useChris Lattner
the lowerallocations pass to eliminate malloc/free warnings and hackish code git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11409 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13Make the cwriter use the lowerinvoke pass so that it can either use ↵Chris Lattner
"disabled exceptions" or "expensive exceptions" controlled by an option. Also refactor and eliminate a bunch of cruft. This is a temporary solution and causes millions of warnings to pour out of programs that use exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190). Subsequent changes will make this stink much less git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11405 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13Add support for a bunch more functionsChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11395 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11393 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13Add support for fopen/fclose. Specifically with fopen, we were marking all ↵Chris Lattner
of the operands as incomplete, though fopen is known to only read them. This just adds fclose for symmetry, though it doesn't gain anything. This makes the dsgraphs for 181.mcf much more precise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11390 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-13Fix compilation of 126.gcc: intrinsic functions cannot throw, so they are notChris Lattner
allowed in invoke instructions. Thus, if we are inlining a call to an intrinsic function into an invoke site, we don't need to turn the call into an invoke! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11384 91177308-0d34-0410-b5e6-96231b3b80d8

any attempts by LLI to use varargs (possibly left over from the introduction of IntrinsicLowering??) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11370 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-13Add head-of-file comments and Doxygen comments. Tighten up a lot of whitespace.Brian Gaeke
Rename SetMachineOperandConst's formal parameters to match other methods here. Mark some methods as being used only by the SPARC back-end. Fix a missing-paren bug in OutputValue(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11363 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-12Add support for memcpy and memmove intrinsics. Why isn't the cwriter usingChris Lattner
the intrinsiclowering code?? :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11362 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-12Add parent pointer to MachineInstr that points to owningAlkis Evlogimenos
MachineBasicBlock. Also change opcode to a short and numImplicitRefs to an unsigned char so that overall MachineInstr's size stays the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11357 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-12Change MachineBasicBlock's vector of MachineInstr pointers into anAlkis Evlogimenos
ilist of MachineInstr objects. This allows constant time removal and insertion of MachineInstr instances from anywhere in each MachineBasicBlock. It also allows for constant time splicing of MachineInstrs into or out of MachineBasicBlocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11340 91177308-0d34-0410-b5e6-96231b3b80d8
