bug with egcs gcc for mips16

[Rik van de Wiel]

Hi,

I encountered an internal error when using options -mips16 and -Os 
together.

Info egcs compiler:
	- gcc version egcs-2.91.57 19980901 (egcs-1.1 release)
	- configured with --host=sparc-sun-solaris2.5.1 --target=mips

Internal error occurs when calling:

	mips-gcc -mips16 -Os -c test.c

File test.c is attached to this mail message (This is the smallest
example I could construct for which this error occurs).

Error message:

internal error--insn does not satisfy its constraints:
(insn 47 18 50 (set (reg:SI 24 t8)
        (reg:SI 64 hi)) 228 {movsi_internal2+1} (nil)
    (nil))
/home/wiel/tmp/egcs-1.1b/gcc/toplev.c:1360: Internal compiler error in function fatal_insn



Best regards,

Rik
