Hello all
This is the first time that I report a GCC bug...
Unix system
-----------
SunOS ife.ee.ethz.ch 5.7 Generic_106541-11 sun4u sparc SUNW,Ultra-60
GCC configuring options
-----------------------
configure --prefix=/usr/pack/GCC-2.95.2-to
GCC version
-----------
GCC version 2.95.2 19991024 (release)
GCC system type
---------------
sparc-sun-solaris2.7/2.95.2/specs
command line triggering the crash
---------------------------------
gcc -g -O2 -c mbx.c
GCC output
----------
mbx.c: In function `mbx_hdrpos':
mbx.c:1443: internal error--unrecognizable insn:
(insn 78 76 80 (set (reg:SI 129)
(minus:SI (const_int 4 [0x4])
(const_int -4096 [0xfffff000]))) -1 (nil)
(expr_list:REG_EQUAL (const_int 4100 [0x1004])
(nil)))
.i-file
-------
is attatched as mbx.i.gz
mbx.c is part of imap-2000.tar.gz
Thanks for responding to my report. I am a frequent user of GCC and I am
very satisfied with GNU stuff in general and GCC in particular. I simply
must say this in case nobody else does...
Cheers,
Beat
