Extended Description

thakis@ubu:~$ cat test.S
.MACRO foo
.ENDM

thakis@ubu:~$ arm-linux-gnueabihf-g++ -c test.S

But:

$ ~/src/llvm-build/bin/clang -target arm-linux-androideabi -c test.S
test.S:1:1: error: unknown directive
.MACRO FFTSTAGE
^
test.S:2:1: error: unknown directive
.ENDM
^

Used in openmax.

openmax also uses .ELSE , .ENDIF etc. AsmParser.cpp already converts opcodes to lowercase before looking them up, maybe it should do the same for directives?

[nico]

I see if we can change openmax. That seems like a nicer approach, if viable.

[nico]

Err, I meant "I will check if we can change openmax".

[rengolin]

Thanks Nico, having one way to parse macros would be very helpful.

We ended up changing this in openmax_dl, so this no longer is an issue for us. I'm a bit surprised that clang can get away with only supporting lower-case directives given that gas supports arbitrary case, but it's a pleasant surprise :-)
