similar to: [LLVMdev] Is NASM supported by LLVM?

If by "NASM format" you mean Intel syntax, then yes. In my experience most LLVM tools refer to it with the option "-x86-asm-syntax=intel". For example, tools/llvm-objdump has this flag. --Sean Silva On Wed, Jun 20, 2012 at 10:12 PM, Thomson <lilotom at gmail.com> wrote: > I saw some LLVM generated assembly in NASM format, but did find this > support in the

Could generated assembly with option "-x86-asm-symtab=intel" be assembled by nasm directly?

Given the number of people that are starting to be involved in Syslinux development, I wanted to start a discussion about a common coding style, for C code in particular. Currently, a lot of the code in Syslinux is written in different styles, partly because my own style has changed over the years. There are pretty much two alternatives that I think are realistic: a) Linux kernel coding style:

I saw many definitions derived from Instruction defines OutputOperandList and InputOperandList (usually in the xxxInstrFormats.td), but I don't see where they are referenced. Anything I missed here?

I just found that some samples used link.exe from Visual Studio to generate the final image, does LLVM has a replacement for link.exe to generate the final binary? -- Thanks Thomson -------------- next part -------------- An HTML attachment was scrubbed...

I saw there is reference to dead def on registers in LLVM source code. I am not aware of this concept from the traditional course material. What are the properties of dead def?

To generate code for a target which doesn't have immediate constant as instruction operand, do I (the target specific back-end, XXXTarget) need to provide code to break up the SDNode with constant (like ISD::ADD $reg1, #1) to 2 SDNodes (ISD::LOAD $reg2, #1; ISD::ADD $reg1, $reg2) in my XXXTargetLowering::LowerOperation, or LLVM target-independent framework can do such transformation

I found that LLVM optimized the IR by replacing printf with puts. I wondered which pass did this optimization? And is it common that puts is faster (and some other metric) than printf? -- Thanks Thomson -------------- next part -------------- An HTML attachment was scrubbed...

The blow snippet in target.td shows the regList in RegisterClass is typed as dag. Why not make it a simple list, such as list<Register>? class RegisterClass<string namespace, list<ValueType> regTypes, int alignment, dag regList> Thanks, -Thomson -------------- next part -------------- An HTML attachment was scrubbed...

Is there any reason why link.exe is undesirable? You can

I tried to build an LLVM pass in visual studio with cmake, but it seems add_LLVM_loadable_module macro doesn't support non-unix and non-cygwin platform. Is loadable module necessary for LLVM pass? Could I just build a static library and pass it to opt? If static library is not supported, is there any way to build an LLVM pass through visual studio? Or through clang with cmake? -- Thanks

Hi, trying to build syslinux on Linux. Please help. bash-2.05b$ uname -a Linux bongo 2.4.32-ARXc3 COHERENT #4-ARX (Build 2660) Sun May 21 15:35:22 CEST 2006 i686 i686 i386 GNU/Linux bash-2.05b$ BUILD/syslinux-3.11/opt/nasm-0.98.38-2/bin/nasm -version NASM version 0.98.38 compiled on Jun 26 2006 But failed with: + make NASM=/home/axel/p/rpm/BUILD/syslinux-3.11/opt/nasm/bin /nasm

where can I get the lastest nasm to compile syslinux 1.75. http://www.cryogen.com/Nasm is not accessible and the latest on ftp://ftp.kernel.org/pub/software/devel/nasm/source/ is nasm-0.98.tar.bz2 Thanks, Jeff [ jchua at fedex.com ]

Hi folks, here's a patch which cleans up the nasm call from Makefiles. Abusing libtool and then having to drop in some additional wrapper script to rewrite the commandline again is rather stupid. cu -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service - http://www.metux.de/

Is Nasm always available when the target architecture is IA-32? For example, FLAC has FLAC__lpc_compute_autocorrelation_asm_ia32_sse_lag_NN() functions that require NASM presence, and FLAC__lpc_compute_autocorrelation_intrin_sse_lag_NN() functions that require x86 intrinsics support. FLAC makes use of the former (if NASM is available) but doesn't try to use the latter when NASM is not found.

Couldn't one conditionally output some macros for the assembler to translate the reg names rather than having another .td file? or is '%' not a valid part of a macro on NASM?

The required efforts equal to ones required to write new assembler. "Too weak to be usable" means "it's not possible to represent many important constructs with masm/nasm/fasm". -- With best

Thanks for Anton's reply. Does anybody have an idea of roughly how much effort is required to make intel asm printer to be usable? If it is within weeks, probably I can give it a try.
