Modern versions of OSX/Darwin's ld (ld64 > 97.17) have an optimisation present that allows the back end to omit relocations (and replace them with an absolute difference) for FDE some text section refs.

When switching modes in an assembly file (e.g. arm to thumb mode) we would always emit the opcode from the original mode. Consider this small example: $ cat align.s .code 16 foo: add r0, r0 .align 3 add r0, r0 $ llvm-mc -triple armv7-none-linux align.s -filetype=obj -o t.o $ llvm-objdump -triple thumbv7 -d t.o Disassembly of section .text: foo: 0: 00 44 add r0, r0 2: 00 f0 20 e3 blx #4195904 6: 00 00 movs r0, r0 8: 00 44 add r0, r0 This shows that we have actually emitted an arm nop (e320f000) instead of a thumb nop. Unfortunately, this encodes to a thumb branch which causes bad things to happen when compiling assembly code with align directives. The fix is to notify the ARMAsmBackend when we switch mode. The MCMachOStreamer was already doing this correctly. This patch makes the same change for the MCElfStreamer. There is still a bug in the way nops are emitted for alignment because the MCAlignment fragment does not store the correct mode. The ARMAsmBackend will emit nops for the last mode it knew about. In the example above, we still generate an arm nop if we add a `.code 32` to the end of the file.

* MC asm parser: allow ?'s in symbol names, and handle @'s in names in MS asmHans Wennborg2013-10-18
| | | | | | | | | | | | | | | | | | | | This is another (final?) stab at making us able to parse our own asm output on Windows. Symbols on Windows often contain @'s and ?'s in their names. Our asm parser didn't like this. ?'s were not allowed, and @'s were intepreted as trying to reference PLT/GOT/etc. We can't just add quotes around the bad names, since e.g. for MinGW, we use gas to assemble, and it doesn't like quotes in some places (notably in .def directives). This commit makes us allow ?'s in symbol names, and @'s in symbol names for MS assembly.

| | | | | | | | | | | | | | | | | | | | | | | | | | The reason this got reverted was that the @feat.00 symbol which was emitted for every TU became quoted, and on cygwin/mingw we use the gas assembler which couldn't handle the quotes. This commit fixes the problem by only emitting @feat.00 for win32, where we use clang -cc1as to assemble. gas would just drop this symbol anyway, so there is no loss there. With @feat.00 gone, there shouldn't be quoted symbols showing up on cygwin since it uses the Itanium ABI, which doesn't put these funny characters in symbols. > Because of win32 mangling, we produce symbol and section names with > funny characters in them, most notably @ characters. > > MC would choke on trying to parse its own assembly output.

* Remove some really nasty uses of hasRawTextSupport.Rafael Espindola2013-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When MC was first added, targets could use hasRawTextSupport to keep features working before they were added to the MC interface. The design goal of MC is to provide an uniform api for printing assembly and object files. Short of relaxations and other corner cases, a object file is just another representation of the assembly. It was never the intention that targets would keep doing things like if (hasRawTextSupport()) Set flags in one way. else Set flags in another way. When they do that they create two code paths and the object file is no longer just another representation of the assembly. This also then requires testing with llc -filetype=obj, which is extremelly brittle. This patch removes some of these hacks by replacing them with smaller ones. The ARM flag setting is trivial, so I just moved it to the constructor. For Mips, the patch adds two temporary hack directives that allow the assembly to represent the same things as the object file was already able to. The hope is that the mips developers will replace the hack directives with the same ones that gas uses and drop the -print-hack-directives flag. I will also try to implement a target streamer interface, so that we can move this out of the common code. In summary, for any new work, two rules of the thumb are * Don't use "llc -filetype=obj" in tests. * Don't add calls to hasRawTextSupport. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192035 91177308-0d34-0410-b5e6-96231b3b80d8

* [MC][AsmParser] Hook for post assembly file processingJack Carter2013-10-04
| | | | | | | | | | | | | | | | | | | | | | This patch handles LLVM standalone assembler (llvm-mc) ELF flag setting based on input file directive processing. Mips assembly requires processing inline directives that directly and indirectly affect the output ELF header flags. This patch handles one ".abicalls". To process these directives we are following the model the code generator uses by storing state in a container as we go through processing and when we detect the end of input file processing, AsmParser is notified and we update the ELF header flags through a MipsELFStreamer method with a call from MCTargetAsmParser::emitEndOfAsmFile(MCStreamer &OutStreamer). This patch will allow other targets the same functionality. Jack git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191982 91177308-0d34-0410-b5e6-96231b3b80d8

E.g., on a vector shuffle operation with a memory operand, disassembled outputs are: * Without the option: vpshufd $-0x79, (%rsp), %xmm0 * With the option: vpshufd $-0x79, (%rsp), %xmm0 ## Latency: 5 The printed latency is extracted from the schedule model available in the disassembler context. Thus, this option has no effect if there is not a scheduling model for the target. This boils down to one may need to specify the CPU string, so that this option could have an effect. Note: Latency < 2 are not printed. This part of <rdar://problem/14687488>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191859 91177308-0d34-0410-b5e6-96231b3b80d8

* MC: Add support for treating $ as a reference to the PCDavid Majnemer2013-09-25
| | | | | | | | | | | | | | | | | | The binutils assembler supports a mode called DOLLAR_DOT which treats the dollar sign token as a reference to the current program counter if the dollar sign doesn't precede a constant or identifier. This commit adds a new MCAsmInfo flag stating whether or not a given target supports this interpretation of the dollar sign token; by default, this flag is not enabled. Further, enable this flag for PPC. The system assembler for AIX and binutils both support using the dollar sign in this manner. This fixes PR17353. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191368 91177308-0d34-0410-b5e6-96231b3b80d8
