| | | | llvm-svn: 25514
* Make this more efficient in the following ways:Chris Lattner2006-01-221-22/+37
| | | | | | | | | 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. llvm-svn: 25512

* Several non-functionality changing changes:Chris Lattner2006-01-221-311/+151
| | | | | | | | | 1. Use the varargs version of getOrInsertFunction to simplify code. 2. remove #include 3. Reduce the number of #ifdef's. 4. remove extraneous vertical whitespace. llvm-svn: 25508

| | | | | | | unsigned llvm.cttz.* intrinsic, fixing the 2005-05-11-Popcount-ffs-fls regression last night. llvm-svn: 25398
* For PR411:Reid Spencer2006-01-161-5/+16
| | | | | | | | | | | | | | | | 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. llvm-svn: 25366

* Use the ClonedCodeInfo object to avoid scans of the inlined code whenChris Lattner2006-01-131-62/+67
| | | | | | | 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. llvm-svn: 25284

* Fix a bug I noticed by inspection: if the first instruction in the inlinedChris Lattner2006-01-131-5/+3
| | | | | | | | 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. llvm-svn: 25280

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
