2006-11-27Preliminary support for inline asm in the cbe. The target specific uglinessAndrew Lenharth
is still in Writer, but issolated to a single function. This might be split into something in each target directory. This is sufficient to get through archie and an strcpy impl on linux-x86.

2006-11-27For PR950:Reid Spencer
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31931 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31542 91177308-0d34-0410-b5e6-96231b3b80d8

2006-11-02For PR786:Reid Spencer
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31380 91177308-0d34-0410-b5e6-96231b3b80d8

Make necessary changes to support DIV -> [SUF]Div. This changes llvm to have three division instructions: signed, unsigned, floating point. The bytecode and assembler are bacwards compatible, however. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31195 91177308-0d34-0410-b5e6-96231b3b80d8

has a different prototype than the one #included from <setjmp.h>. This patch fixes siod and a number of other test cases on Linux that were failing the CBE because of this _setjmp issue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31112 91177308-0d34-0410-b5e6-96231b3b80d8

DLL* linkages got full (I hope) codegeneration support in C & both x86 assembler backends. External weak linkage added for future use, we don't provide any codegeneration, etc. support for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30374 91177308-0d34-0410-b5e6-96231b3b80d8

2006-09-04Completely rearchitect the interface between targets and the pass manager.Chris Lattner
This pass: 1. Splits TargetMachine into TargetMachine (generic targets, can be implemented any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by things using libcodegen and other support). 2. Instead of having each target fully populate the passmgr for file or JIT output, move all this to common code, and give targets hooks they can implement. 3. Commonalize the target population stuff between file emission and JIT emission. 4. All (native code) codegen stuff now happens in a FunctionPassManager, which paves the way for "fast -O0" stuff in the CFE later, and now LLC could lazily stream .bc files from disk to use less memory. 5. There are now many fewer #includes and the targets don't depend on the scalar xforms or libanalysis anymore (but codegen does). 6. Changing common code generator pass ordering stuff no longer requires touching all targets. 7. The JIT now has the option of "-fast" codegen or normal optimized codegen, which is now orthogonal to the fact that JIT'ing is being done. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30081 91177308-0d34-0410-b5e6-96231b3b80d8
