Hi,
I am testing a cross-compiler targetting arm-wince-pe and based on
gcc-trunk revision r144975 and when
compiling a project I get the following error :
vinc...@vincent-pc:~/projects$ arm-mingw32ce-gcc -std=gnu99 -save-temps
-I/home/vincent/local/wince/include -DNDEBUG -O3 -c cegcc-errno-bug.c
-DDLL_EXPORT -DPIC -o libeet_la-eet_lib.o
cegcc-errno-bug.c: In function 'eet_close':
cegcc-errno-bug.c:134: error: unrecognizable insn:
(insn 6 5 7 3 cegcc-errno-bug.c:114 (set (reg/f:SI 138)
(symbol_ref:SI ("errno") [flags 0x4c0] <var_decl 0xb7db26e0
errno>)) -1 (nil))
cegcc-errno-bug.c:134: internal compiler error: in extract_insn, at
recog.c:2048
Of course I could report a bug but since original sources are patched the
bug might be due to one
of the modifications.
Anyway if someone knows how I could fix this, the only thing I see is the
fact the problem seems to be
related to errno and on wince platform by default there is no errno.
So the project I am compiling declare it like this and is defined in a
library.
/home/vincent/local/wince/include/errno.h:

} // L134 : where gcc crash
If I comment the errno variable inside the switch and replace it by 1 for
instance, it compiles fine.
Where should I start ?
