Remove m32r{,le}-*-linux* support from GCC
Commit Message
From: Andrew Pinski <apinski@marvell.com>
m32r support never made it to glibc and the support for the Linux kernel
was removed with 4.18. It does not remove much but no reason to keep
around a port which never worked or one which the support in other
projects is gone.
OK? Checked to make sure m32r-linux and m32rle-linux were rejected
when building.
contrib/ChangeLog:
* config-list.mk: Remove m32r-linux and m32rle-linux
from the list.
gcc/ChangeLog:
* config.gcc: Add m32r-*-linux* and m32rle-*-linux*
to the Unsupported targets list.
Remove support for m32r-*-linux* and m32rle-*-linux*.
* config/m32r/linux.h: Removed.
* config/m32r/t-linux: Removed.
libgcc/ChangeLog:
* config.host: Remove m32r-*-linux* and m32rle-*-linux*.
* config/m32r/libgcc-glibc.ver: Removed.
* config/m32r/t-linux: Removed.
