2003-07-25(1) Major fix to the way unused regs. are marked and found for the FPVikram S. Adve
Single and FP double reg types (which share the same reg class). Now all methods marking/finding unused regs consider the regType within the reg class, and SparcFloatRegClass specializes this code. (2) Remove machine-specific regalloc. methods that are no longer needed. In particular, arguments and return value from a call do not need machine-specific code for allocation. (3) Rename TargetRegInfo::getRegType variants to avoid unintentional overloading when an include file is omitted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7334 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

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

2003-07-16Fixed the number translation scheme for the integer condition code registers: itMisha Brukman
now works in instructions which require a 2-bit or 3-bit INTcc code. Incidentally, that means that the representation of INTcc registers is now the same in both integer and FP instructions. Thus, code became much simpler and cleaner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7185 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-15Correctly handle calls to functions which are further away than 2**32 bits willMisha Brukman
allow, i.e. make a sequence of instructions to enable an indirect call using jump-and-link and 2 temporary registers (which we save and ultimately restore). Warning: if the delay slot of a function call is used to do meaningful work and not just a NOP, this behavior is incorrect. However, the Sparc backend does not yet utilize the delay slots effectively, so it is not necessary to make an overly complicated algorithm for something that's not used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7178 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-11If we have a constant pointer reference to a function, we were printingBrian Gaeke
out the entire llvm disassembly for the function at global constant-output time, which caused the assembler to barf in 164.gzip.

2003-07-10Several important bug fixes:Vikram S. Adve
(1) Cannot use ANDN(ot), ORN, and XORN for boolean ops, only bitwise ops. (2) Conditional move instructions must distinguish signed and unsigned condition codes, e.g., MOVLE vs. MOVLEU. (3) Conditional-move-on-register was using the cond-move-on-cc opcodes, which produces a valid-looking instruction with bogus registers! (4) Here's a really cute one: dividing-by-2^k for negative numbers needs to add 2^k-1 before shifting, not add 1 after shifting. Sadly, these are the same when k=0 so our poor test case worked fine. (5) Casting between signed and unsigned values was not correct: completely reimplemented. (6) Zero-extension on unsigned values was bogus: I was only doing the SRL and not the SLLX before it. Don't know WHAT I was thinking! (7) And the most important class of changes: Sign-extensions on signed values. Signed values are not sign-extended after ordinary operations, so they must be sign-extended before the following cases: -- passing to an external or unknown function -- returning from a function -- using as operand 2 of DIV or REM -- using as either operand of condition-code setting operation (currently only SUBCC), with smaller than 32-bit operands Also, a couple of improvements: (1) Fold cast-to-bool into Not(bool). Need to do this for And, Or, XOR also. (2) Convert SetCC-Const into a conditional-move-on-register (case 41) if the constant is 0. This was only being done for branch-on-SetCC-Const when the branch is folded with the SetCC-Const. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7159 91177308-0d34-0410-b5e6-96231b3b80d8
