2002-10-13Don't mark JMPLCALL and JMPLRET as branches.Vikram S. Adve

2002-10-13(1) Try to evaluate constant when multiplying 2 constants.Vikram S. Adve
(2) Use intelligent multiply selection code for array allocas. (3) Don't use cache padding for alloca'd stack slots! (4) Bug fix in handling call arguments: was not copying sixth FP arg to int reg. when calling a function with no prototype. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4130 91177308-0d34-0410-b5e6-96231b3b80d8

2002-10-13Make sure to handle small negative values hiding as large unsigned longs --Vikram S. Adve
this is a common case created by the front-end. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4127 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-13Major fix: extract ConstantExpr nodes and decompose them into symbolicVikram S. Adve
instructions so that (a) constant folding is done automatically before code generation, and (b) selection does not have to deal with them. Also, check for ConstantPointerRefs in additional to GlobalValues when creating a GEP to load a global address. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4126 91177308-0d34-0410-b5e6-96231b3b80d8

2002-10-05Bug fix: In preventing static global variables from being printed twice,Vikram S. Adve
I also prevented external globals from being printed twice, but they should (extern declaration and definition). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4043 91177308-0d34-0410-b5e6-96231b3b80d8

2002-09-28Live ranges for Return value and return address of a Call are no longerVikram S. Adve
created here. Instead they are created in LiveRangeInfo.cpp. This simplifies the code here quite a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3965 91177308-0d34-0410-b5e6-96231b3b80d8

2002-09-27Overhaul integer conversions to match C++ ISO standard.Vikram S. Adve
Don't allow direct FP-to-uint conversion (must be eliminated by preselection). Address arithmetic for arrays is now entirely 64-bit so no sign-ext needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3961 91177308-0d34-0410-b5e6-96231b3b80d8

2002-09-20Fix cwriter to not output FP constants in ascii, output them in hex instead.Chris Lattner
This fixes a number of FP precision problems, making the output of the power benchmark closer to the right answer. Unfortunately, this only addresses FP constants used directly in functions. Constants referred to by global constants (such as an array of FP values) aren't helped by this. Until this happens power won't work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3871 91177308-0d34-0410-b5e6-96231b3b80d8

2002-09-20Another change that doesn't affect functionality. Since we are only lookingChris Lattner
at types in the symbol table, only traverse the type plane, saving a loop nest. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3858 91177308-0d34-0410-b5e6-96231b3b80d8

2002-09-20Allow copy coalescing in more cases: if sum of node degrees is more thanVikram S. Adve
than #available regs, compute the sum excluding duplicates and if that is less than #regs, go ahead and coalesce. Add method IGNode::getCombinedDegree to count excluding duplicates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3842 91177308-0d34-0410-b5e6-96231b3b80d8
