Hi Eric, Hi Richard, We have received a bug report against the mips64vrel-elf toolchain which is reproducible with the mainline sources. Since it (appears to) involve MIPS code generation and I know almost nothing about MIPS I am passing it on to you in the hopes that you might be able to fix it, or at least point me in the right direction.
To reproduce the problem compile the attached two files with:
% mips64vrel-elf 128201-1.c 128201-2.c -Tddb.ld -mabi=32 -march=vr5000
Then run it with the simulator:
% mips64vrel-elf-run a.out
FPR 4 (format single) being accessed with format double - setting to
unknown (PC = 0xa0100364)
-2.333333 (-2.333333)
Note the error message from the simulator. The problem appears to
be $f4 register used by the sub.d instruction. I suspect, but do not
know for sure, that this is somehow connected with the store_df_high
pattern in mips.md.
Any clues or solutions ?
Cheers
Nick
