RE: [openrisc] eCos & gcc bug
I have been looking at this a bit further and have further information which
may help.
The problem occurs when trying to return a cyg_ucount8 in a fn. which is
expecting to return a cyg_uint8 (or the equivalent signed types). These base
types are different by default (which is used by OpenRISC):
cyg_uint8 is unsigned char
cyg_ucount8 is unsigned int
cyg_int8 is signed char
cyg_count8 is signed int
The error occurs in emit_move_insn():
if (mode == BLKmode || (GET_MODE (y) != mode && GET_MODE (y) != VOIDmode))
abort ();
I admit I'm not an expert here but I presume that it is bombing out because
the 'modes' of the two input operands are wrong. I can't really help much
more than this.
I tried the following:
1) Changing the auto variable type into cyg_uint8. This made no difference
to the reported error.
2) Changing the return type into cyg_ucount8. This compiled without error.
I have 'attached' a couple of patches. Run 'patch -p0 < <patchfile>' in the
following directories for each respective <patchfile>. I haven't put MIME
attachments on as they can be rejected by mailing lists. Snip the code
between the <<patchfile>> and </<patchfile>> brackets to get the
'attachments':
packages/language/c/libc/time/current/include:
language_c_libc_time_include.patch
packages/language/c/libc/time/current/src:
language_c_libc_time_src.patch
There is an issue in that I have changed a header file. I did a look to see
if anything called cyg_libc_time_itoa() and AFAICT nothing did.
I am not suggesting that these patches should be permanent but they will get
a build going without resorting to knocking bits out and may help identify
the real problem in the toolset.
