2007-01-28Propagate changes from my local tree. This patch includes:Anton Korobeynikov
1. New parameter attribute called 'inreg'. It has meaning "place this parameter in registers, if possible". This is some generalization of gcc's regparm(n) attribute. It's currently used only in X86-32 backend. 2. Completely rewritten CC handling/lowering code inside X86 backend. Merged stdcall + c CCs and fastcall + fast CC. 3. Dropped CSRET CC. We cannot add struct return variant for each target-specific CC (e.g. stdcall + csretcc and so on). 4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in on first attribute has meaning 'This is hidden pointer to structure return. Handle it gently'. 5. Fixed small bug in llvm-extract + add new feature to FunctionExtraction pass, which relinks all internal-linkaged callees from deleted function to external linkage. This will allow further linking everything together. NOTEs: 1. Documentation will be updated soon. 2. llvm-upgrade should be improved to translate csret => sret. Before this, there will be some unexpected test fails. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33597 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-10Add a simple pass to make sure that all (non-library) calls to malloc and freeAndrew Lenharth
are visible to analysis as intrinsics. That is, make sure someone doesn't pass free around by address in some struct (as happens in say 176.gcc). This doesn't get rid of any indirect calls, just ensure calls to free and malloc are always direct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27560 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-16For each loop, keep track of all the IV expressions inserted indexed byEvan Cheng
stride. For a set of uses of the IV of a stride which is a multiple of another stride, do not insert a new IV expression. Rather, reuse the previous IV and rewrite the uses as uses of IV expression multiplied by the factor. e.g. x = 0 ...; x ++ y = 0 ...; y += 4 then use of y can be rewritten as use of 4*x for x86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26803 91177308-0d34-0410-b5e6-96231b3b80d8

2005-11-28Random sampling (aka Arnold and Ryder) profiling. This is still ↵Andrew Lenharth
preliminary, but it works on spec on x86 and alpha. The idea is to allow profiling passes to remember what profiling they inserted, then a random sampling framework is inserted which consists of duplicated basic blocks (without profiling), such that at each backedge in the program and entry into every function, the framework chooses whether to use the instrumented code or the instrumentation free code. The goal of such a framework is to make it reasonably cheap to do random sampling of very expensive profiling products (such as load-value profiling). The code is organized into 3 parts (2 passes) 1) a linked set of profiling passes, which implement an analysis group (linked, like alias analysis are). These insert profiling into the program, and remember what they inserted, so that at a later time they can be queried about any instruction. 2) a pass that handles inserting the random sampling framework. This also has options to control how random samples are choosen. Currently implemented are Global counters, register allocated global counters, and read cycle counter (see? there was a reason for it). The profiling passes are almost identical to the existing ones (block, function, and null profiling is supported right now), and they are valid passes without the sampling framework (hence the existing passes can be unified with the new ones, not done yet). Some things are a bit ugly still, but that should be fixed up soon enough. Other todo? making the counter values not "magic 2^16 -1" values, but dynamically choosable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24493 91177308-0d34-0410-b5e6-96231b3b80d8
