2003-07-24Cleanups:Brian Gaeke
Mangler.cpp: Constify parameter to makeNameProper, and use const_iterator. Make Count an unsigned int, and use utostr(). Don't name parameters things that start with underscore. Mangler.h: All of the above, and also: Add Emacs mode-line. Include <set>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7301 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-24Use unified CWriter-X86/Printer name mangler. Do not bother usingBrian Gaeke
SlotCalculator in CWriter. (Unfortunately, all this means a lot of X86/Printer's methods have to be de-constified again. Oh well.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7299 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-24Allow folding several instructions into casts, which can simplify a lotChris Lattner
of codes. For example, short kernel (short t1) { t1 >>= 8; t1 <<= 8; return t1; } became: short %kernel(short %t1.1) { %tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1] %tmp.5 = cast short %tmp.3 to int ; <int> [#uses=1] %tmp.7 = shl int %tmp.5, ubyte 8 ; <int> [#uses=1] %tmp.8 = cast int %tmp.7 to short ; <short> [#uses=1] ret short %tmp.8 } before, now it becomes: short %kernel(short %t1.1) { %tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1] %tmp.8 = shl short %tmp.3, ubyte 8 ; <short> [#uses=1] ret short %tmp.8 } which will become: short %kernel(short %t1.1) { %tmp.3 = and short %t1.1, 0xFF00 ret short %tmp.3 } This implements cast-set.ll:test4 and test5 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7290 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-24Constify most methods. We could have constified doInitialization andBrian Gaeke
doFinalization too except that would have made them shadow, not override, the parent class :-P. Allow *any* constant cast expression between pointers and longs, or vice-versa, or any widening (not just same-size) conversion that isLosslesslyConvertibleTo approves. This fixes oopack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7288 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-23Add, rewrite, and/or reformat many comments.Brian Gaeke
Stop passing ostreams around: we already have one perfectly good ostream and we can all share it. Stop stashing a pointer to TargetData in the Pass object, because that will lead to a crash if there are no functions in the module (ouch!) Instead, use addRequired() and getAnalysis(), like we always should have done. Move the check for ConstantExpr up before the check for isPrimitiveType, because we need to be able to catch e.g. ubyte (cast bool false to ubyte), whose type is primitive but which is nevertheless a ConstantExpr, by calling our specialized handler instead of the AsmWriter. This would result in assembler errors when we would try to output something like ".byte (cast bool false to ubyte)". GC some unused variable declarations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7265 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-18Please, save your applause^H^H^H^H^H^H^H^Hflames for the end...Brian Gaeke
Avoid a fall-through in the (stubby) treatment of the longjmp intrinsic call which causes llc & lli to core-dump. Add a sort-of treatment of cast double to ulong. I am not really sure what a user should expect to see upon casting a negative FP value to unsigned long long. But with what is given here, I was able to write a program that could cast -123.456 to ulong and back and get -123.0, which seems like a step in the right direction. GCC seems to give you 0. I don't know if I'd consider that useful. These cases were coming up in GNU coreutils-5.0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7205 91177308-0d34-0410-b5e6-96231b3b80d8
