2002-04-28Eliminate the PromoteInstance class, incorporating it into the PromotePassChris Lattner
class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2375 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-28Eliminate visited, CurrentValue, and WriteSets as instance variables ofChris Lattner
PromoteInstance. Make them local variables that are passed around as appropriate. Especially in the case of CurrentValue, this makes the code simpler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2374 91177308-0d34-0410-b5e6-96231b3b80d8

2002-04-27* Rename MethodPass class to FunctionPassChris Lattner
- Rename runOnMethod to runOnFunction * Transform getAnalysisUsageInfo into getAnalysisUsage - Method is now const - It now takes one AnalysisUsage object to fill in instead of 3 vectors to fill in - Pass's now specify which other passes they _preserve_ not which ones they modify (be conservative!) - A pass can specify that it preserves all analyses (because it never modifies the underlying program) * s/Method/Function/g in other random places as well git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2333 91177308-0d34-0410-b5e6-96231b3b80d8

2002-04-25Don't record instructions for copying method arguments in theVikram S. Adve
AddedInstrns sets for the first machine instruction. It is hard to ensure that the right order is preserved, and sure enough, the order was broken. Instead, use a separate set for the function entry. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2318 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-25Don't pad spills and temp. stack areas for alignment.Vikram S. Adve
Freeze auto vars and spill areas when their sizes are used for computing other offsets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2317 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-25Major changes to how int and FP arguments are handled. VarargsVikram S. Adve
function calls were simply wrong; other functions were just not using all available registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2316 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-25Added functions to compute which register, if any, to useVikram S. Adve
for a particular argument in a list of arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2315 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-25Insert copy operations for FP arguments to a varargs function,Vikram S. Adve
to copy the FP arg. to an integer. Necessary so that the register allocator has two different live ranges for the FP value and the int. argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2314 91177308-0d34-0410-b5e6-96231b3b80d8

2002-04-25Optional args are no longer allocated as they are discovered.Vikram S. Adve
(This can be improved to avoid making the initial pass over the method.) Also, ensure automatic vars and reg. spills areas are not extended if their sizes are used for computing some other offset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2310 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-24* Abort program on verification errorsChris Lattner
* Verify that load, store, and GEP instructions indices are correct, because they _continually_ bite me on this pool allocations stuff git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2309 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-18Add some basic checks of CallInst's.Chris Lattner
Assert now returns from the current function on error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2308 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2307 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-18* Convert the verifier to use an InstVisitor to be better structuredChris Lattner
* Implement checking that a binary operator's two sides are the same type * Actually check that an instruction does not have a name if it has a void return type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2305 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2302 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-18Move asmwriter/getStrValue cruft into AsmWriter.cpp file.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2300 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-18Pull all of the getStrValue implementation cruft out of Constants.cpp andChris Lattner
put it into the AsmWriter. This code is kinda gross and could probably be cleaned up, but not now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2299 91177308-0d34-0410-b5e6-96231b3b80d8
2002-04-18Add a fixme so that we don't forget this is broken.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2298 91177308-0d34-0410-b5e6-96231b3b80d8
