* Changes to support making the shift instructions be true BinaryOperators.Reid Spencer2007-02-021-1/+4
| | | | | | | | | | | | This feature is needed in order to support shifts of more than 255 bits on large integer types. This changes the syntax for llvm assembly to make shl, ashr and lshr instructions look like a binary operator: shl i32 %X, 1 instead of shl i32 %X, i8 1 Additionally, this should help a few passes perform additional optimizations. llvm-svn: 33776

* Propagate changes from my local tree. This patch includes:Anton Korobeynikov2007-01-281-11/+29
| | | | | | | | | | | | | | | | | | | | | | 1. New parameter attribute called 'inreg'. It has meaning "place this parameter in registers, if possible". This is some generalization of gcc's regparm(n) attribute. It's currently used only in X86-32 backend. 2. Completely rewritten CC handling/lowering code inside X86 backend. Merged stdcall + c CCs and fastcall + fast CC. 3. Dropped CSRET CC. We cannot add struct return variant for each target-specific CC (e.g. stdcall + csretcc and so on). 4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in on first attribute has meaning 'This is hidden pointer to structure return. Handle it gently'. 5. Fixed small bug in llvm-extract + add new feature to FunctionExtraction pass, which relinks all internal-linkaged callees from deleted function to external linkage. This will allow further linking everything together. NOTEs: 1. Documentation will be updated soon. 2. llvm-upgrade should be improved to translate csret => sret. Before this, there will be some unexpected test fails. llvm-svn: 33597

| | | | | | | that we default to an ANY_EXTEND if no parameter attribute is set on the result value of a function. llvm-svn: 32836
* Restore previous behavior of defaulting to ZEXT. This works around twoReid Spencer2007-01-031-7/+2
| | | | | | | | things: (1) preventing PR1071 and (2) working around missing parameter attributes for bool type. (2) will be fixed shortly. When PR1071 is fixed, this patch should be undone. llvm-svn: 32831
* Two changes:Reid Spencer2007-01-031-5/+12
| | | | | | | | | | | 1. Switch expression and cases are compared signed and are sign extended. 2. For function results needing extended, do SIGN_EXTEND if the SExtAttribute is set and ZERO_EXTEND if the ZExtAttribute is set, otherwise just let the Legalizer do ANY_EXTEND. This fixes the recent regression in kimwitu++ and probably the llvm-gcc bootstrap issue we had today. llvm-svn: 32830
* For PR950:Reid Spencer2006-12-311-53/+55
| | | | | | | | | | | | | | | | | | Three changes: 1. Convert signed integer types to signless versions. 2. Implement the @sext and @zext parameter attributes. Previously the type of an function parameter was used to determine whether it should be sign extended or zero extended before the call. This information is now communicated via the function type's parameter attributes. 3. The interface to LowerCallTo had to be changed in order to accommodate the parameter attribute information. Although it would have been convenient to pass in the FunctionType itself, there isn't always one present in the caller. Consequently, a signedness indication for the result type and for each parameter was provided for in the interface to this method. All implementations were changed to make the adjustment necessary. llvm-svn: 32788
* For PR950:Reid Spencer2006-12-231-104/+89
| | | | | | | | This patch removes the SetCC instructions and replaces them with the ICmp and FCmp instructions. The SetCondInst instruction has been removed and been replaced with ICmpInst and FCmpInst. llvm-svn: 32751

* For PR950:Reid Spencer2006-11-271-56/+140
| | | | | | | | | | The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. llvm-svn: 31931

| | | | | | | | This patch converts the old SHR instruction into two instructions, AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not dependent on the sign of their operands. llvm-svn: 31542
* For PR786:Reid Spencer2006-11-021-6/+0
| | | | | | | | | | Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. llvm-svn: 31380

* Allow the getRegForInlineAsmConstraint method to return a register class withChris Lattner2006-11-021-4/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | no fixes physreg. Treat this as permission to use any register in the register class. When this happens and it is safe, allow the llvm register allcoator to allocate the register instead of doing it at isel time. This eliminates a ton of copies around common inline asms. For example: int test2(int Y, int X) { asm("foo %0, %1" : "=r"(X): "r"(X)); return X; } now compiles to: _test2: foo r3, r4 blr instead of: _test2: mr r2, r4 foo r2, r2 mr r3, r2 blr GCC produces: _test2: foo r4, r4 mr r3,r4 blr llvm-svn: 31366
