ARM assembly fails to build for iOS/ARM

[Geoff Nixon]

I can confirm this. Neither the Clang integrated assembler nor the 
Apple-provided version of GAS know anything about these pseudo-ops.

This errors on at least 5 .asm files; after that, I stopped trying to 
weed them out. I think --disable-assembly is a must for now.

Subject: ARM assembly fails to build for iOS/ARM


Hi,the ARM assembly in version 5.1.3 fails to build for iOS/ARM. The 
MachOassembly does not know anything about .protected (or .hiddenor 
.internal for that matter).Workaround is to build with 
--disable-assembly but that's of course notideal. 5.0.5 had no ARM 
assembly for that part of the code and thusbuilt fine too.Compiler
