1.15 +From: Kaz Kojima <kkojima at rr dot iij4u dot or dot jp>

1.20 +Hi,
1.21 +
1.22 +The appended patch is to fix PR target/15647
1.23 + http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15647
1.24 +for linux.
1.25 +__udivsi3 is exported from libgcc_s.so.1 and gcc generates the code
1.26 +which assumes r1 will be not clobbered when calling __udivsi3 in SH3
1.27 +case. This is bad because r1 is clobbered by PLT.
1.28 +The another functions listed in the standard libgcc-std.ver which
1.29 +possively have similar problem are __ashlsi3, __ashrsi3 and __lshrsi3,
1.30 +though these are used only by SH1/2.
1.31 +The patch below simply uses an SH specific libgcc-std.ver which drops
1.32 +these functions. SH linux uses a linker script libgcc_s.so having
1.33 +libgcc.a as a suppementary library, so these functions given by
1.34 +libgcc.a when needed in the link time.
1.35 +Although mainline has one failure in bulding zlib which can be avoided
1.36 +with -fno-reorder-blocks for sh3-unknown-linux-gnu target, x86 cross
1.37 +to sh3-unknown-linux-gnu can be build successfully on mainline with
1.38 +this patch except the above failure. 3.4-branch successfully bootstraps
1.39 +with it and there are no new failures on the native sh4-unknown-linux-gnu.
1.40 +The patch is highly sh-linux specific and seems to be safe. I'll check
1.41 +it into mainline.
1.42 +The original PR is also for sh3 netbsd. I'd like to leave it for the
1.43 +netbsd experts.
1.44 +
1.45 +I think that it's too late for 3.3.4. Mark, is it also late for
1.46 +3.4.1?
1.47 +
1.48 +Regards,
1.49 + kaz
