I see something similar with gcc 4.5.3 when compiling mrtg:
./src/rateup.c:1136:1: error: insn does not satisfy its constraints:
(insn 11219 11218 3096 307 ./src/rateup.c:913 (set (mem/c:SI (reg:DI 2 %g2) [23
%sfp+-10660 S4 A32])
(reg:SI 65 %f33 [+4 ])) 50 {*movsi_insn} (nil))
./src/rateup.c:1136:1: internal compiler error: in
reload_cse_simplify_operands, at postreload.c:396
(this has originally been reported as http://gnats.netbsd.org/46719)
Is this the samme issue? Any chance of a fix for the 4.5 branch?
