[Bug rtl-optimization/55106] ice: Maximum number of LRA constraint passes is achieved (15)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55106 --- Comment #7 from Vladimir Makarov vmakarov at gcc dot gnu.org 2012-12-21 14:27:51 UTC --- (In reply to comment #5) I'm still hitting this failure when building GMP 5.1.0 for i686-w64-mingw32: libtool: compile: i686-w64-mingw32-gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I../../../../src/gmp/mpn -I.. -D__GMP_WITHIN_GMP -I../../../../src/gmp -DOPERATION_sbpi1_div_qr -O2 -march=nocona -mtune=core2 -fomit-frame-pointer -momit-leaf-frame-pointer -c sbpi1_div_qr.c -o sbpi1_div_qr.o div_qr_2u_pi1.c: In function '__gmpn_div_qr_2u_pi1': div_qr_2u_pi1.c:67:1: internal compiler error: Maximum number of LRA constraint passes is achieved (30) } ^ Please submit a full bug report, with preprocessed source if appropriate. The build for x86_64-w64-mingw32 did not encounter this problem. I'm building on 64-bit Debian using a self-built linux to Windows cross-compilers. Could you provide a preprocessed source code. I'd try to reproduce this. In any case, it will be not fixed quickly. I am on vacation next two weeks. Sorry.
