The consequence is that UTF-8-encoded identifiers come out in UTF-8: scshunt at natural-flavours:~$ gcc -fextended-identifiers -std=c99 -x c -c -o test.o - int i\u03bb; scshunt at natural-flavours:~$ nm test.o 00000004 C iλ scshunt at natural-flavours:~$ As you can see, the nm output includes the literal lambda.

Why is it that high (>127) bytes in symbol names get mangled by LLVM into _XX_, where XX is the hex representation of the character? Is this required by ELF or some similar standard? This behavior is inconsistent with GCC. Sean -------------- next part -------------- An HTML attachment was scrubbed... URL:

Okay... then we should probably support that as well. Might need to be a bit careful to make sure the assembly files work corr...
