Description Stanislav Brabec 2008-11-01 15:11:51 UTC 
When compiling attached file with "-march=iwmmxt -mtune=iwmmxt -O -fno-omit-frame-pointer", then following error appears on line "score= sqr - ((diff*(int64_t)diff)>>(level+3))":

svq1enc.c: In function 'encode_block':
svq1enc.c:265: error: insn does not satisfy its constraints:
(insn 1636 1634 334 22 (set (reg:SI 43 wcgr0)

                (const_int -3888 [0xfffffffffffff0d0])) [0 D.8214+0 S4 A32])) 407 {*iwmmxt_movsi_insn} (nil)
    (nil))
svq1enc.c:265: internal compiler error: in reload_cse_simplify_operands, at postreload.c:392

When compiling without -fno-omit-frame-pointer, everything works correctly.

Using built-in specs.

Can you check this with a later compiler. 4.2.x is closed. Works for me with current trunk.

Just encountered similar problem while cross compiling gcc 4.4.0 with glibc 2.9.

Can you give a pre-processed file for further investigations ? Your report is incomplete without it and hence I'll have to retain the waiting status on this one.

Comment 7 Enrico Scholz 2009-11-28 23:15:45 UTC 
ICE has been verified with gcc 4.4.2.

Some analysis have been done in bug #40836 (comments 20 + 21): the WLDRW operation which would be required for this insn allows only 10 (effective 8) bit but not 12 bit for the immediate offset.  E.g. the '-3888' in

   WLDRW  wcgr0, [fp, #-3888]

is not possible.
Comment 8 Andrew Pinski 2024-03-15 21:49:11 UTC 
iwmmxt support has been deprecated in GCC 13 .
