Hi Ramana. FYI, gcc trunk fails to bootstrap with:
../../../../gcc-4.8~/libgcc/libgcc2.c: In function '__mulvdi3': ../../../../gcc-4.8~/libgcc/libgcc2.c:397:1: internal compiler error: in df_uses_record, at df-scan.c:3179
A cross compiler fails when building EEMBC with:
(insn 1166 1165 1167 155 (set (reg:CC 24 cc) (compare:CC (reg:SI 2148 [ D.6766 ]) (const_int 5000 [0x1388]))) iirflt01/bmark.c:501 -1 (nil)) iirflt01/bmark.c:1138:1: internal compiler error: in extract_insn, at recog.c:2131
The last revision that bootstrapped was 187203. 187223 and 187275 failed.

This looks like http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53278 which was fixed last week by rev 187299
Are we still seeing this failure ?

That is more of a worry. I'll try to have a look today.

I saw that failure a while ago, but the snapshot from 20120513 is OK again.

Thanks - Looks like one more person managed to bootstrap fine as well http://gcc.gnu.org/ml/gcc-testresults/2012-05/msg01479.html

Here's a reduced testcase and an untested fix which is also upstream now at :
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53376
* arm.md (movsicc): Adjust operands for the comparison.
extern int x; static long long p; static long long *h1 ; static long long *h2 ;
void foo (void) { int i ; for( i = 0 ; i < x ; i++ ) { if( (p >> 3) > 5000) p += 5000; *h2 = *h1 ; h2++; } }
