How to build gcc toolchain with -fno-leading-underscore

[yabin]

e-gcc uses -fleading-underscore as default when using current build process, which means it always mangles a C function name with a leading underscore (main -> _main).
How can i build e-gcc toolchain with --no-leading-underscore as default?

Thanks in advance!

Hi yabin,

Although this does not build you a toolchain that uses that flag, you can modify in gcc/gcc/config/epiphany/epiphany.h the definition of USER_LABEL_PREFIX to "" so the compiler adds an empty prefix to function names.
