Subject: gcc-3.0: internal compiler error: unrecognized insn
To: [EMAIL PROTECTED]
X-Mailer: bug 3.3.9
Delivered-To: [EMAIL PROTECTED]
Package: gcc-3.0
Version: 1:3.0-0pre010526
Severity: normal
Building XFree86 4.1.0 from source, with gcc-3.0, using the options
"-O3 -funroll-loops -march=k6":
s3v_dac.c: In function `S3VCommonCalcClock':
s3v_dac.c:110: Unrecognizable insn:
(insn 585 583 587 (set (reg:SI 212)
(zero_extend:SI (reg/v:QI 59))) -1 (nil)
(nil))
s3v_dac.c:110: Internal compiler error in extract_insn, at recog.c:2210
s3v_dac.c is 109 lines long, so line 110 is after EOF.
If I enter this directory and issue the "make all CDEBUGFLAGS=-O2"
command, it compiles successfully. In fact, it also builds with
'make all CDEBUGFLAGS="-O3 -funroll-loops"', and with "-g -march=k6",
and with "-O3 -march=k6", and with "-funroll-loops -march=k6", and with
"-O -funroll-loops -march=k6".
I can only get it to blow up if I combine "-march=k6" and "-funroll-loops"
and "-O2" or higher optimization.
I can send the 109-line s3v_dac.c file if you need it, but it won't
compile without a slew of XFree86 headers.

At least this is fixed in the gcc-3.0.4 packages (and in gcc-3.1 as
well).
