1.10 +Hi,
1.11 +
1.12 +attached you find the files I needed to add to crosstool-0.38
1.13 +in order to build a sh4-linux gcc-4.0.2-glibc-2.3.5 tool chain.
1.14 +
1.15 +Files attached:
1.16 +
1.17 +sh4-gcc4.dat:
1.18 + * gcc4 needs --with-multilib-list=m4,m4-nofpu otherwise a linux
1.19 + kernel won't build as it uses the -m4-nofpu option.
1.20 +
1.21 +gcc-pr21623.patch:
1.22 + * Kaz Kojima provided a patch [really, a workaround -dank] for http://gcc.gnu.org/PR21623
1.23 +
1.24 +glibc-2.3.5-sh-memset.patch:
1.25 + * A patch for glibc-2.3.5 which corrects memset. From SUGIOKA Toshinobu.
