* Check for _strtoi64 in the cmake build if strtoll is missingReid Kleckner2013-08-072-14/+10
| | | | | | | | | | Previously this check was guarded by MSVC, which doesn't distinguish between the compiler and the headers/library.

| | | | | | | | | | | | | | | | | | | | | generic UTF8-capable terminal. Summary: This is a second attempt to get this right. After reading the Unicode Standard I came up with the code that uses definitions of "printable" and "column width" more suitable for terminal output (i.e. fixed-width fonts and special treatment of many control characters). The implementation here can probably be used for Windows and MacOS if someone can test it properly. The patch addresses PR14910.

* R600/SI: Use VSrc_* register classes as the default classes for typesTom Stellard2013-08-066-44/+247
| | | | | | | | | | | | | | | | | Since the VSrc_* register classes contain both VGPRs and SGPRs, copies that used be emitted by isel like this: SGPR = COPY VGPR Will now be emitted like this: VSrC = COPY VGPR This patch also adds a pass that tries to identify and fix situations where a VGPR to SGPR copy may occur. Hopefully, these changes will make it impossible for the compiler to generate illegal VGPR to SGPR copies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187831 91177308-0d34-0410-b5e6-96231b3b80d8

* Change the linkage of these global values to 'internal'.Bill Wendling2013-08-062-6/+9
| | | | | | | | | | | | | | | | | | | The globals being generated here were given the 'private' linkage type. However, this caused them to end up in different sections with the wrong prefix. E.g., they would be in the __TEXT,__const section with an 'L' prefix instead of an 'l' (lowercase ell) prefix. The problem is that the linker will eat a literal label with 'L'. If a weak symbol is then placed into the __TEXT,__const section near that literal, then it cannot distinguish between the literal and the weak symbol. Part of the problems here was introduced because the address sanitizer converted some C strings into constant initializers with trailing nuls. (Thus putting them in the __const section with the wrong prefix.) The others were variables that the address sanitizer created but simply had the wrong linkage type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187827 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove some std stream usage from Support and TableGenReid Kleckner2013-08-064-19/+25

* Debug Info Finder|Verifier: handle DbgLoc attached to instructions.Manman Ren2013-08-0617-50/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also remove checking of llvm.dbg.sp since it is not used in generating dwarf. Current state of Finder: DebugInfoFinder tries to list all debug info MDNodes used in a module. To list debug info MDNodes used by an instruction, DebugInfoFinder provides processDeclare, processValue and processLocation to handle DbgDeclareInst, DbgValueInst and DbgLoc attached to instructions. processModule will go through all DICompileUnits in llvm.dbg.cu and list debug info MDNodes used by the CUs. TODO: 1> Finder has a list of CUs, SPs, Types, Scopes and global variables. We need to add a list of variables that are used by DbgDeclareInst and DbgValueInst. 2> MDString fields should be null or isa<MDString> and MDNode fields should be null or isa<MDNode>. We currently use empty string or int 0 to represent null. 3> Go though Verify functions and make sure that they check field types. 4> Clean up existing testing cases to remove llvm.dbg.sp and make sure each testing case has a llvm.dbg.cu. Re-apply r187609 with fix to pass ocaml binding. vmcore.ml generates a debug location with scope being metadata !{}, in verifier we treat this as a null scope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187812 91177308-0d34-0410-b5e6-96231b3b80d8
