[OpenRISC] Clang does not understand .word directive in crt0.S in newlib source

[OpenRISC] Clang does not understand .word directive in crt0.S in newlib source

[Rieger, David]

Hello everyone

I am trying to compile newlib using clang/LLVM 3.8.1 with the or1k target. However, compilation fails on newlib-source/libgloss/or1k/crt0.S with clang complaining it does not know the ".word" assembler directive:

../newlib-source/libgloss/or1k/crt0.S:83:19: error: unknown directive
_or1k_stack_size: .word 8192
                  ^
../newlib-source/libgloss/or1k/crt0.S:84:29: error: unknown directive
_or1k_exception_stack_size: .word 8192

Any help in how I can fix this so clang compiles the file would be greatly appreciated.

Thanks
David

Replacing .word with .int did the trick.

Hi David,

Looks like your assembler is broken. One option is to not use the
integrated assembler, but instead use the standalone assembler from
the GNU tool chain.

Rather than using .int as in your following message, you might like to
use .2byte or .4byte which are more explicit about their exact meaning.

HTH,


Jeremy
