2006-01-22Make this more efficient in the following ways:Chris Lattner
1. Do not statically construct a map when the program starts up, this is expensive and cannot be optimized. Instead, create a list. 2. Do not insert entries for all function in the module into a hashmap that lives the full life of the compiler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25512 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-22Several non-functionality changing changes:Chris Lattner

Don't do floor->floorf conversion if floorf is not available. This checks the compiler's host, not its target, which is incorrect for cross-compilers Not sure that's important as we don't build many cross-compilers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25456 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-16For PR411:Reid Spencer
This patch is an incremental step towards supporting a flat symbol table. It de-overloads the intrinsic functions by providing type-specific intrinsics and arranging for automatically upgrading from the old overloaded name to the new non-overloaded name. Specifically: llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64 llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64 llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64 llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64 llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64 New code should not use the overloaded intrinsic names. Warnings will be emitted if they are used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25366 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-13Permit inlining functions that contain dynamic allocations now thatChris Lattner
InlineFunction handles this case safely. This implements Transforms/Inline/dynamic_alloca_test.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25288 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-13If inlining a call to a function that contains dynamic allocas, wrap theChris Lattner
resultant code with llvm.stacksave/llvm.stackrestore intrinsics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25286 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-13Use ClonedCodeInfo to avoid another walk over the inlined code, this thisChris Lattner
time in common C cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25285 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-13Use the ClonedCodeInfo object to avoid scans of the inlined code whenChris Lattner
it doesn't contain any calls. This is a fairly common case for C++ code, so it will probably speed up the inliner marginally in these cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25284 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-13Allow the code cloning interfaces to capture some important info about theChris Lattner
code being cloned if the client wants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25281 91177308-0d34-0410-b5e6-96231b3b80d8
2006-01-13Fix a bug I noticed by inspection: if the first instruction in the inlinedChris Lattner
function was not an alloca, we wouldn't check the entry block for any allocas, leading to increased stack space in some cases. In practice, allocas are almost always at the top of the block, so this was never noticed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25280 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-06Enhance the shift-shift folding code to allow a no-op cast to occur in betweenChris Lattner
the shifts. This allows us to fold this (which is the 'integer add a constant' sequence from cozmic's scheme compmiler): int %x(uint %anf-temporary776) { %anf-temporary777 = shr uint %anf-temporary776, ubyte 1 %anf-temporary800 = cast uint %anf-temporary777 to int %anf-temporary804 = shl int %anf-temporary800, ubyte 1 %anf-temporary805 = add int %anf-temporary804, -2 %anf-temporary806 = or int %anf-temporary805, 1 ret int %anf-temporary806 } into this: int %x(uint %anf-temporary776) { %anf-temporary776 = cast uint %anf-temporary776 to int %anf-temporary776.mask1 = add int %anf-temporary776, -2 %anf-temporary805 = or int %anf-temporary776.mask1, 1 ret int %anf-temporary805 } note that instcombine already knew how to eliminate the AND that the two shifts fold into. This is tested by InstCombine/shift.ll:test26 -Chris git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25128 91177308-0d34-0410-b5e6-96231b3b80d8
