Bug ID: 64348 Summary: Case scal-to-vec1.c failed on arm-linux-gnueabi with -fPIC Product: gcc Version: 5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: amker at gcc dot gnu.org Case scal-to-vec1.c failed because of ICE on arm-linux-gnueabi with -fPIC. The compilation command line is: ./arm-none-linux-gnueabi-gcc scal-to-vec1.c -fno-diagnostics-show-caret -fdiagnostics-color=never -O3 -S -fPIC -o ./scal-to-vec1.S -mcpu=cortex-a8/a9 -marm Thumb mode is fine, processors like cortex-a7/a15 are fine. The ICE info is like below: /home/binche01/work/oban-work/src/gcc/gcc/testsuite/gcc.c-torture/execute/scal-to-vec1.c: In function ‘main’: /home/binche01/work/oban-work/src/gcc/gcc/testsuite/gcc.c-torture/execute/scal-to-vec1.c:86:1: internal compiler error: in split_reg, at lra-constraints.c:4879 0xbad893 split_reg /home/binche01/work/oban-work/src/gcc/gcc/lra-constraints.c:4879 0xbade33 split_if_necessary /home/binche01/work/oban-work/src/gcc/gcc/lra-constraints.c:4983 0xbafb13 inherit_in_ebb /home/binche01/work/oban-work/src/gcc/gcc/lra-constraints.c:5478 0xbb04fc lra_inheritance() /home/binche01/work/oban-work/src/gcc/gcc/lra-constraints.c:5639 0xb9914b lra(_IO_FILE*) /home/binche01/work/oban-work/src/gcc/gcc/lra.c:2303 0xb48738 do_reload /home/binche01/work/oban-work/src/gcc/gcc/ira.c:5402 0xb48b0e execute /home/binche01/work/oban-work/src/gcc/gcc/ira.c:5573 Gcc is configured as below: --target=arm-none-linux-gnueabi --prefix=... --with-sysroot=... --disable-libssp --disable-libmudflap --enable-checking=yes --enable-languages=c,c++ --with-gmp=... --with-mpfr=... --with-mpc=... --with-isl=... --with-cloog=... --disable-libgomp --with-arch=armv7-a It is from thread https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01448.html File this PR for tracking.
