| Hello *, | | I recently found a bug in gcc2.2.2 on several mips R3000 | architectures: mips-sony-news, mips-sgi-irix4, mips-dec-ultrix. | | Compiling the following piece of code (now senseless, because i tried to | cut it down to only a few lines; this is the shortest version I have) | with "gcc -O -funroll-loops -c neugit.c" | will yield: | ---- | neugit.c: In function `gitter': | neugit.c:35: internal error--unrecognizable insn: | (insn 440 438 361 (set (reg:SI 6) | (mem:SI (plus:SI (reg:SI 29) | (const_int 90120)))) -1 (nil) | (nil)) | gcc: Internal compiler error: program cc1 got fatal signal 4 This appears to be fixed by the current development version of GCC 2.3, after I fixed a bug in the move constraints. -- Michael Meissner email: meissner@osf.org phone: 617-621-8861 Open Software Foundation, 11 Cambridge Center, Cambridge, MA, 02142 You are in a twisty little passage of standards, all conflicting.
