...und this in clang? My problem is actually how to load external symbol in Clang's integrated-as? I've tried to learn some trivial c code's assembly output, but find there are many linker related symbol and really confusing. Thanks in advance!

Hi,all. Since the recent clang(3.2) has an integrated assembler for ARM, but I can't find document about this assembler's syntax, such assembler's directive, pseudo-instruction, (I assumed it follows the ARM Unified Assembly Language in instructions), where can I get such information? Thanks! ashi

Hi,all, I've some problem when using clang compile my ARM assembly code: 1 .qn directive In GAS, .qn directive is used to create typed and/or indexed register aliases for use in Advanced SIMD Extension (Neon) instructions.( http://sourceware.org/binutils/docs/as/ARM-Directives.html#ARM-Directives) But clang's integrated-as seems have different syntax, for example, my code: input .qn

Hi, Jim, Why "asm" name is a horrible hack? Do you have any suggestion for cross-platform support of my ARM assembly code?

Underscores are normal and expected. Using an "asm" name

Bernie, is it related to ARM pipeline? I'm interesting in this, is there any other additional information? On Fri, Mar 8, 2013 at 4:59 AM, Tim Northover <t.p.northover at gmail.com>wrote: > Hi Ashi,

Hi Ashi, > ld: illegal text-relocation to _data_table in table.o from foo in > use_table.o for architecture armv7 It looks like you're using iOS. I'm not familiar with the exact workings of that platform, but I think a similar message would occur in ELF-land. If iOS *is* comparable, your issue is that symbols in dynamically loaded objects can't (usually) be referenced directly

>Apple requires a leading _ for all external symbols. So "works as >expected". Thanks. Do you have any advice to make the code work both under Apple and GNU gcc?

But it's unreasonable that if I declare a function 'foo()', then I have to implement '_foo()' in assembly, doesn't it?
