With r162897 reverted subsequent gcc-4.6 snapshots up to the 4.6.2 release bootstrap fine with Ada enabled and a few patches applied, specifically: 1. revert the core of r162897 (original has a few harmless failing hunks) 2. backport of pr43804 fix 3. backport of pr47612 fix which also fixes pr48554 4. the m68k-ada patch as posted here earlier 5. backport r178834 cfgcleanup HAVE_cc0 fix (will also be in 4.6.3) Note I'm not applying the insv fragment of r171341 any more. I saw some test suite regressions from 4.6 with it applied so I've dropped it. However, meanwhile 4.7 has broken. 4.7-20110730 builds fine as a cross, but every snapshot from 20110806 to 20111203 ICE as follows: /tmp/objdir/./gcc/xgcc -B/tmp/objdir/./gcc/ -B/home/mikpe/pkgs/linux-x86/cross-m68k/m68k-unknown-linux/bin/ -B/home/mikpe/pkgs/linux-x86/cross-m68k/m68k-unknown-linux/lib/ -isystem /home/mikpe/pkgs/linux-x86/cross-m68k/m68k-unknown-linux/include -isystem /home/mikpe/pkgs/linux-x86/cross-m68k/m68k-unknown-linux/sys-include -c -g -O2 -W -Wall -gnatpg -nostdinc a-assert.adb -o a-assert.o +===========================GNAT BUG DETECTED==============================+ | 4.7.0 20111203 (experimental) (m68k-unknown-linux) GCC error: | | in fp_size_to_prec, at ada/gcc-interface/misc.c:781 | | Error detected around :0 | So now I'm bisecting trunk to identify the cause of this regression.
