A .i file which breaks on Sparc.
Created attachment 4695 [details]
A .i file which compiles on Sparc.
Should be fixed in http://gcc.gnu.org/ml/gcc-patches/2000-10/msg01085.html Will appear in the next gcc rpm. Fixed in gcc-2.96-63 in rawhide. |
This occurs when building the UW IMAP toolkit on Sparc (it compiles on i386 and alpha). I have a workaround in place, so this is not that urgent. I'll attach a .i file which breaks (mbx.i.sparc), and one with a workaround (mbx.i.good). The compile: [prospector@lisa c-client]$ cc -g -O2 -m32 -mtune=ultrasparc -fPIC -I/usr/kerberos/include -I/usr/include/openssl -c -o mbx.o mbx.c -v --save-temps Reading specs from /usr/lib/gcc-lib/sparc64-redhat-linux/2.96/specs gcc version 2.96 20000731 (Red Hat Linux 7.0) /usr/lib/gcc-lib/sparc64-redhat-linux/2.96/cpp0 -lang-c -v -I/usr/kerberos/include -I/usr/include/openssl -D__GNUC__=2 -D__GNUC_MINOR__=96 -D__GNUC_PATCHLEVEL__=0 -D__ELF__ -Dunix -D_LONGLONG -D__sparc__ -Dlinux -D__ELF__ -D__unix__ -D_LONGLONG -D__sparc__ -D__linux__ -D__unix -D__linux -Asystem(unix) -Asystem(posix) -D__OPTIMIZE__ -g -D__SIZE_TYPE__=unsigned int -D__PTRDIFF_TYPE__=int -D__GCC_NEW_VARARGS__ -Acpu(sparc) -Amachine(sparc) -D__PIC__ -D__pic__ mbx.c mbx.i GNU CPP version 2.96 20000731 (Red Hat Linux 7.0) (cpplib) (sparc64 GNU/Linux with ELF) ignoring nonexistent directory "/usr/local/include" ignoring nonexistent directory "/usr/sparc64-redhat-linux/include" #include "..." search starts here: #include <...> search starts here: /usr/kerberos/include /usr/include/openssl /usr/lib/gcc-lib/sparc64-redhat-linux/2.96/include /usr/include End of search list. /usr/lib/gcc-lib/sparc-redhat-linux/2.96/cc1 mbx.i -gstabs+ -quiet -dumpbase mbx.c -m32 -mtune=ultrasparc -g -O2 -version -fPIC -o mbx.s GNU C version 2.96 20000731 (Red Hat Linux 7.0) (sparc-redhat-linux) compiled by GNU C version 2.96 20000731 (Red Hat Linux 7.0). mbx.c: In function `mbx_hdrpos': mbx.c:1371: Unrecognizable insn: (insn 116 114 118 (set (reg:SI 135) (minus:SI (const_int 4 [0x4]) (const_int -4096 [0xfffff000]))) -1 (nil) (expr_list:REG_EQUAL (const_int 4100 [0x1004]) (nil))) mbx.c:1371: Internal compiler error in extract_insn, at recog.c:2108 Please submit a full bug report.
