Subject: libgcc/Makefile.in: Delete dead `MACHMODE_H` variable
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=493aae4b034d62054d5e7e54dc06cd9a8be54e29;p=thirdparty%2Fgcc.git

libgcc/Makefile.in: Delete dead `MACHMODE_H` variable

This dates back to the creation of top-level `libgcc` in
fa9585134f6f58fa0d3da3ca4ad5493855aea2dc. I strongly suspect that this
does nothing.

Andrew Pinksi adds:

It is indeed used then.

(For background context, my overall goal here is hoping libgcc can depend on
fewer/no stuff that is generated by `gcc/Makefile`. This is me trying to
pluck some low-hanging fruit -- this is the only direct mention of
`insn-modes.h` in libgcc.)
