Hi Zhenqiang. I've had a look at the difference between testsuite
results on our current softfp Natty builders and the new hard float
Precise builders. The diff and notes is at:
http://people.linaro.org/~michaelh/incoming/hard-float-builder-diff.txt
There's a lot of commonality:
/usr/bin/ld: cannot find {S,g}crt1.o: builder fault. I've fixed this.
sorry, unimplemented: Thumb-1 hard-float VFP ABI errors: tests where
they set the architecture to ARMv5T and use our default Thumb mode.
This causes the compiler to fail as it doesn't support Thumb-1 with
hard float.
arm_iwmmxt_ok5222.c:1:0: sorry, unimplemented: iWMMXt and hardware
floating point
Some are real:
+FAIL: gcc.c-torture/compile/sync-3.c -O0 (test for excess errors)
/tmp/cc3ufndj.s:436: Error: co-processor offset out of range
+FAIL: gcc.dg/pr48335-2.c (test for excess errors)

Some are marked as unsupported but shouldn't be:
+UNSUPPORTED: gcc.dg/tree-ssa/gen-vect-11a.c
+UNSUPPORTED: gcc.dg/tree-ssa/gen-vect-11b.c
+UNSUPPORTED: gcc.dg/tree-ssa/gen-vect-11.c
+UNSUPPORTED: gcc.dg/tree-ssa/gen-vect-11c.c
+UNSUPPORTED: gcc.dg/tree-ssa/gen-vect-25.c
+UNSUPPORTED: gcc.dg/tree-ssa/gen-vect-26.c
+UNSUPPORTED: gcc.dg/tree-ssa/gen-vect-28.c
+UNSUPPORTED: gcc.dg/tree-ssa/gen-vect-2.c
+UNSUPPORTED: gcc.dg/tree-ssa/gen-vect-32.c
Could you look into the unsupported ones please? I'll fix the crt1
problems and respin the build.
