* Change std::vector to SmallVector<4> and remove some unused methods.Eli Bendersky2012-12-051-1/+1
| | | | | | | | This is more consistent with other vectors in this code. In addition, I ran some tests compiling a large program and >96% of fragments have 4 or less fixups, so SmallVector<4> is a good optimization. llvm-svn: 169433

* RegisterPressureTracker: unify virtual registers and physical regunits.Andrew Trick2012-12-051-241/+179
| | | | | | Now that live register units are tracked individually, the code can be simplified. llvm-svn: 169426
* RegisterPresssureTracker: Track live physical register by unit.Andrew Trick2012-12-051-94/+87
| | | | | | | | This is much simpler to reason about, more efficient, and fixes some corner cases involving implicit super-register defs. Fixed rdar://12797931. llvm-svn: 169425

* Correct ARM NOP encodingDavid Sehr2012-12-051-1/+1
| | | | | | | | | | The encoding of NOP in ARMAsmBackend.cpp is missing a trailing zero, which causes the emission of a coprocessor instruction rather than "mov r0, r0" as indicated in the comment. The test also checks for the wrong encoding. http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121203/157919.html llvm-svn: 169420

* 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> llvm-svn: 169405

* Remove unused MachineInstr constructors.Jakob Stoklund Olesen2012-12-051-27/+0
| | | | | | | | A MachineInstr can only ever be constructed by CreateMachineInstr() and CloneMachineInstr(), and those factories don't use the removed constructors. llvm-svn: 169395
* 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 llvm-svn: 169393
* - Added calls to doInitialization/doFinalization to immutable passesPedro Artigas2012-12-052-15/+52
| | | | | | | | | - fixed ordering of calls to doFinalization to be the reverse of the pass run order due to potential dependencies - fixed machine module info to operate in the doInitialization/doFinalization model, also fixes some FIXMEs reviewed by Evan Cheng <evan.cheng@apple.com> llvm-svn: 169391

* 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. Reviewed by Nadav, Thanks a lot! llvm-svn: 169317

* 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. llvm-svn: 169312
* 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. llvm-svn: 169304

* 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. llvm-svn: 169281

* Add a comment about the requirement that the Windows.h header be last.Chandler Carruth2012-12-041-0/+2
| | | | | | | This comment has the dual effect of blocking reorderings with the sort_include script. llvm-svn: 169221
* 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. llvm-svn: 169218
* Add the last part that is needed for vectorization of if-converted code.Nadav Rotem2012-12-041-162/+251
| | | | | | | | | | | | | | | | | Added the code that actually performs the if-conversion during vectorization. We can now vectorize this code: for (int i=0; i<n; ++i) { unsigned k = 0; if (a[i] > b[i]) <------ IF inside the loop. k = k * 5 + 3; a[i] = k; <---- K is a phi node that becomes vector-select. } llvm-svn: 169217
