implicit operands on copies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89880 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-24Do not store R31 into the caller's link area on PPC.Dale Johannesen
This violates the ABI (that area is "reserved"), and while it is safe if all code is generated with current compilers, there is some very old code around that uses that slot for something else, and breaks if it is stored into. Adjust testcases looking for current behavior. I've verified that the stack frame size is right in all testcases, whether it changed or not. 7311323. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89811 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-10Emit correct code when making a ConstantPool entry for a vectorDale Johannesen
constant whose component type is not a legal type for the target. (If the target ConstantPool cannot handle this type either, it has an opportunity to merge elements. In practice any target with 8-bit bytes must support i8 *as data*). 7320806 (partial). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86751 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-10Modify how the prologue encoded the "move" information for the FDE. GCCBill Wendling
generates a sequence similar to this: __Z4funci: LFB2: mflr r0 LCFI0: stmw r30,-8(r1) LCFI1: stw r0,8(r1) LCFI2: stwu r1,-80(r1) LCFI3: mr r30,r1 LCFI4: where LCFI3 and LCFI4 are used by the FDE to indicate what the FP, LR, and other things are. We generated something more like this: Leh_func_begin1: mflr r0 stw r31, 20(r1) stw r0, 8(r1) Llabel1: stwu r1, -80(r1) Llabel2: mr r31, r1 Note that we are missing the "mr" instruction. This patch makes it more like the GCC output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86729 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-18PowerPC inline asm was emitting two output operandsDale Johannesen
for a single "m" constraint; this is wrong because the opcode of a load or store would have to change in parallel.

2009-08-10Make the big switch: Change MCSectionMachO to represent a section *semantically*Chris Lattner
instead of syntactically as a string. This means that it keeps track of the segment, section, flags, etc directly and asmprints them in the right format. This also includes parsing and validation support for llvm-mc and "attribute(section)", so we should now start getting errors about invalid section attributes from the compiler instead of the assembler on darwin. Still todo: 1) Uniquing of darwin mcsections 2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h] 3) there are a few FIXMEs, for example what is the syntax to get the S_GB_ZEROFILL segment type? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78547 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-16Teach MachineInstr::isRegTiedToDefOperand() to correctly parse inline asm ↵Jakob Stoklund Olesen
operands. The inline asm operands must be parsed from the first flag, you cannot assume that an immediate operand preceeding a register use operand is the flag. PowerPC "m" operands are represented as (flag, imm, reg) triples. isRegTiedToDefOperand() would incorrectly interpret the imm as the flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76101 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15get the PPC stub temporary label from the mangler instead of Chris Lattner

2009-07-14Reapply my previous asmprinter changes now with more testing and two Chris Lattner
additional bug fixes: 1. The bug that everyone hit was a problem in the asmprinter where it would remove $stub but keep the L prefix on a name when emitting the indirect symbol. This is easy to fix by keeping the name of the stub and the name of the symbol in a StringMap instead of just keeping a StringSet and trying to reconstruct it late. 2. There was a problem printing the personality function. The current logic to print out the personality function from the DWARF information is a bit of a cesspool right now that duplicates a bunch of other logic in the asm printer. The short version of it is that it depends on emitting both the L and _ prefix for symbols (at least on darwin) and until I can untangle it, it is best to switch the mangler back to emitting both prefixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75646 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14Change the internal interface to makeNameProper to take a bool thatChris Lattner
indicates whether the label is private or not, instead of taking prefix stuff. One effect of this is that symbols will be generated with *just* the private prefix, instead of both the private prefix *and* the user-label-prefix, but this doesn't matter as long as it is consistent. For example we'll now get "Lfoo" instead of "L_foo". These are just assembler temporary labels anyway, so they never even make it into the .o file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75607 91177308-0d34-0410-b5e6-96231b3b80d8
