* Converted an overly aggressive assert to a conditional check in ↵Michael Gottesman2013-06-18
| | | | | | | | | | | | | | | | | | AddCombineTo64bitMLAL. Said assert assumes that ADDC will always have a glue node as its second argument and is checked before we even know that we are actually performing the relevant MLAL optimization. This is incorrect since on ARM we *CAN* codegen ADDC with a use list based second argument. Thus to have both effects, I converted the assert to a conditional check which if it fails we do not perform the optimization. In terms of tests I can not produce an ADDC from the IR level until I get in my multiprecision optimization patch which is forthcoming. The tests for said patch would cause this assert to fail implying that said tests will provide the relevant tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184230 91177308-0d34-0410-b5e6-96231b3b80d8

* Change the arm assembler to support this from the v7c spec:Kevin Enderby2013-06-18
| | | | | | | | | | | | | | | | "When assembling to the ARM instruction set, the .N qualifier produces an assembler error and the .W qualifier has no effect." In the pre-matcher handler in the asm parser the ".w" (wide) qualifier when in ARM mode is now discarded. And an error message is now produced when the ".n" (narrow) qualifier is used in ARM mode. Test cases for these were added. rdar://14064574 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184224 91177308-0d34-0410-b5e6-96231b3b80d8

* Mips ELF: Mark object file as ABI compliant Jack Carter2013-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When producing objects that are abi compliant we are marking neither the object file nor the assembly file correctly and thus generate warnings. We need to set the EF_CPIC flag in the ELF header when generating direct object. Note that the warning is only generated when compiling without PIC. When compiling with clang the warning will be suppressed by supplying: -Wa,-mno-shared -Wa,-call_nonpic Also the following directive should also be added: .option pic0 when compiling without PIC, This eliminates the need for supplying: -mno-shared -call_nonpic on the assembler command line.

* ARM: fix literal load with positive offset encodingAmaury de la Vieuville2013-06-18
| | | | | | | | | | | | When using a positive offset, literal loads where encoded as if it was negative, because: - The sign bit was not assigned to an operand - The addrmode_imm12 operand was not encoding the sign bit correctly This patch also makes the assembler look at the .w/.n specifier for loads. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184182 91177308-0d34-0410-b5e6-96231b3b80d8

* [yaml2obj][ELF] Refer specifically to the section header string table.Sean Silva2013-06-18
| | | | | | | | | | | | | | | A bug in libObject will cause it to assert() if a symbol table's string table and the section header string table are the same section, so we need to ensure that we emit two different string tables (among other things). The problematic code is the hardcoded usage of ".strtab" (`dot_strtab_sec`) for looking up symbol names in ELFObjectFile<ELFT>::getSymbolName. I discussed this with Michael, and he has some local improvements to the ELF code in libObject that, among other things, should fix our handling of this scenario. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184161 91177308-0d34-0410-b5e6-96231b3b80d8
* [yaml2obj][ELF] Ensure more fields are zero'd.Sean Silva2013-06-18
| | | | | | | | | | | | I was spotting garbage in the output. I'd like to just zero the entire ELFYAML::Section to be sure, but it contains non-POD types. (I'm also trying to avoid bloating the ELFYAML::Foo classes with a bunch of constructor code). No test, since this is by its very nature unpredictable. I'm pretty sure that one of the sanitizers would catch it immediately though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184160 91177308-0d34-0410-b5e6-96231b3b80d8
