the following is from the SH mailing list, and involves a problem with optimization issues in the newer gcc compiler. does anyone know if this has been addressed in the most recent snapshots? i'm just about to try to build a toolchain with the gcc-4.2-20051231 snapshot to see if there's any difference. thanks. rday ---------- Forwarded message ---------- Date: Wed, 4 Jan 2006 23:09:50 -0500 From: xxxxxxxxxxxxxxxxx To: linuxsh-dev@lists.sourceforge.net Subject: [linuxsh-dev] SH3 2.6.15 compile error Using Crosstool-38 with GCC-4.0.1 to compile 2.6.15, I received the following: kernel/built-in.o: In function `__xchg': signal.c:(.text+0xb2c0): undefined reference to `__xchg_called_with_bad_pointer' make: *** [.tmp_vmlinux1] Error 1 Googling turned up the possibility of GCC optimization issues causing xchg() errors. I did not experience this with 2.6.14. Any thoughts? ------ Want more information? See the CrossGCC FAQ, http://www.objsw.com/CrossGCC/ Want to unsubscribe?
