* Adjust JIT target triple on OS X to match the current architecture.Bob Wilson2012-12-051-1/+11
| | | | | | | | | For OS X builds, we generate one version of config.h but then build for multiple architectures. This means that the LLVM_HOSTTRIPLE setting may have the wrong architecture. Adjust it dynamically to match the current architecture. <rdar://problem/12715470> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169405 91177308-0d34-0410-b5e6-96231b3b80d8

* Added a option to the disassembler to print immediates as hex.Kevin Enderby2012-12-054-11/+26
| | | | | | | | | | | | | | | | | | | | | | This is for the lldb team so most of but not all of the values are to be printed as hex with this option. Some small values like the scale in an X86 address were requested to printed in decimal without the leading 0x. There may be some tweaks need to places that may still be in decimal that they want in hex. Specially for arm. I made my best guess. Any tweaks from here should be simple. I also did the best I know now with help from the C++ gurus creating the cleanest formatImm() utility function and containing the changes. But if someone has a better idea to make something cleaner I'm all ears and game for changing the implementation. rdar://8109283 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169393 91177308-0d34-0410-b5e6-96231b3b80d8

* For rdar://12329730, last piece.Shuxin Yang2012-12-041-1/+14
| | | | | | | | | | | | | | | | | | | | | | This change attempts to simplify (X^Y) -> X or Y in the user's context if we know that only bits from X or Y are demanded. A minimized case is provided bellow. This change will simplify "t>>16" into "var1 >>16". ============================================================= unsigned foo (unsigned val1, unsigned val2) { unsigned t = val1 ^ 1234; return (t >> 16) | t; // NOTE: t is used more than once. } ============================================================= Note that if the "t" were used only once, the expression would be finally optimized as well. However, with with this change, the optimization will take place earlier.

* Use the 'count' attribute to calculate the upper bound of an array.Bill Wendling2012-12-043-17/+20
| | | | | | | | | | The count attribute is more accurate with regards to the size of an array. It also obviates the upper bound attribute in the subrange. We can also better handle an unbound array by setting the count to -1 instead of the lower bound to 1 and upper bound to 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169312 91177308-0d34-0410-b5e6-96231b3b80d8
* Reapply r160148 (reverted in r163570) fixing spurious breakpoints in modern GDBDavid Blaikie2012-12-041-1/+1
| | | | | | | | | | | | | | | | | This reapplies the fix for PR13303 now with more justification. Based on my execution of the GDB 7.5 test suite this results in: expected passes: 16101 -> 20890 (+30%) unexpected failures: 4826 -> 637 (-77%) There are 23 checks that used to pass and now fail. They are all in gdb.reverse. Investigating a few looks like they were accidentally passing due to extra breakpoints being set by this bug. They're generally due to the difference in end location between gcc and clang, the test suite is trying to set breakpoints on the closing '}' that clang doesn't associate with any instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169304 91177308-0d34-0410-b5e6-96231b3b80d8

* This patch introduces initial-exec model support for thread-local storageBill Schmidt2012-12-0414-15/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | on 64-bit PowerPC ELF. The patch includes code to handle external assembly and MC output with the integrated assembler. It intentionally does not support the "old" JIT. For the initial-exec TLS model, the ABI requires the following to calculate the address of external thread-local variable x: Code sequence Relocation Symbol ld 9,x@got@tprel(2) R_PPC64_GOT_TPREL16_DS x add 9,9,x@tls R_PPC64_TLS x The register 9 is arbitrary here. The linker will replace x@got@tprel with the offset relative to the thread pointer to the generated GOT entry for symbol x. It will replace x@tls with the thread-pointer register (13). The two test cases verify correct assembly output and relocation output as just described. PowerPC-specific selection node variants are added for the two instructions above: LD_GOT_TPREL and ADD_TLS. These are inserted when an initial-exec global variable is encountered by PPCTargetLowering::LowerGlobalTLSAddress(), and later lowered to machine instructions LDgotTPREL and ADD8TLS. LDgotTPREL is a pseudo that uses the same LDrs support added for medium code model's LDtocL, with a different relocation type. The rest of the processing is straightforward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169281 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a 'count' field to the DWARF subrange.Bill Wendling2012-12-042-3/+7
| | | | | | | | | | The count field is necessary because there isn't a difference between the 'lo' and 'hi' attributes for a one-element array and a zero-element array. When the count is '0', we know that this is a zero-element array. When it's >=1, then it's a normal constant sized array. When it's -1, then the array is unbounded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169218 91177308-0d34-0410-b5e6-96231b3b80d8
