* Final Changes For PR495:Reid Spencer2005-07-0817-189/+210
| | | | | | | | | | | | | | | | | | | | | | | | | | | This chagne just renames some sys::Path methods to ensure they are not misused. The Path documentation now divides methods into two dimensions: Path/Disk and accessor/mutator. Path accessors and mutators only operate on the Path object itself without making any disk accesses. Disk accessors and mutators will also access or modify the file system. Because of the potentially destructive nature of disk mutators, it was decided that all such methods should end in the work "Disk" to ensure the user recognizes that the change will occur on the file system. This patch makes that change. The method name changes are: makeReadable -> makeReadableOnDisk makeWriteable -> makeWriteableOnDisk makeExecutable -> makeExecutableOnDisk setStatusInfo -> setStatusInfoOnDisk createDirectory -> createDirectoryOnDisk createFile -> createFileOnDisk createTemporaryFile -> createTemporaryFileOnDisk destroy -> eraseFromDisk rename -> renamePathOnDisk These changes pass the Linux Deja Gnu tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22354 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR495:Reid Spencer2005-07-0729-331/+249
| | | | | | | | | | | | | | | | | | | | | | Get rid of the difference between file paths and directory paths. The Path class now simply stores a path that can refer to either a file or a directory. This required various changes in the implementation and interface of the class with the corresponding impact to its users. Doxygen comments were also updated to reflect these changes. Interface changes are: appendDirectory -> appendComponent appendFile -> appendComponent elideDirectory -> eraseComponent elideFile -> eraseComponent elideSuffix -> eraseSuffix renameFile -> rename setDirectory -> set setFile -> set Changes pass Dejagnu and llvm-test/SingleSource tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22349 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a problem that instcombine would hit when dealing with unreachable code.Chris Lattner2005-07-071-5/+29
| | | | | | | | | | Because the instcombine has to scan the entire function when it starts up to begin with, we might as well do it in DFO so we can nuke unreachable code.

* First round of support for doing scalar FP using the SSE2 ISA extension andNate Begeman2005-07-0611-91/+388
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XMM registers. There are many known deficiencies and fixmes, which will be addressed ASAP. The major benefit of this work is that it will allow the LLVM register allocator to allocate FP registers across basic blocks. The x86 backend will still default to x87 style FP. To enable this work, you must pass -enable-sse-scalar-fp and either -sse2 or -sse3 to llc. An example before and after would be for: double foo(double *P) { double Sum = 0; int i; for (i = 0; i < 1000; ++i) Sum += P[i]; return Sum; } The inner loop looks like the following: x87: .LBB_foo_1: # no_exit fldl (%esp) faddl (%eax,%ecx,8) fstpl (%esp) incl %ecx cmpl $1000, %ecx #FP_REG_KILL jne .LBB_foo_1 # no_exit SSE2: addsd (%eax,%ecx,8), %xmm0 incl %ecx cmpl $1000, %ecx #FP_REG_KILL jne .LBB_foo_1 # no_exit git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22340 91177308-0d34-0410-b5e6-96231b3b80d8

Intrinsics that return void should only return a token chain, not a token chain/retval pair. 3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone. 4.
