* [Bug target/16589] New: segmentation fault on identical array accesses in the ?: operators' body @ 2004-07-16 12:44 loki at inf dot u-szeged dot hu 2005-03-05 19:48 ` [Bug target/16589] [4.0/4.1 regression] [m68k] " pinskia at gcc dot gnu dot org 0 siblings, 1 reply; 5+ messages in thread From: loki at inf dot u-szeged dot hu @ 2004-07-16 12:44 UTC (permalink / raw) To: gcc-bugs There is something wrong around the array access on m68k. If in body of the ?: operator the array "t" is accessed more than once in same way the compiler'll drop some errors. I made several crosscompiler, and I only found that m68k-*-elf doesn't handle the following c code: float *t, a; void good() { a = (t[0] < 0 ? 0 : (a > 1 ? 1 : t[1])); } void bad() { a = (t[0] < 0 ? 0 : (a > 1 ? 1 : t[0])); } Command line: m68k-elf-gcc -O1 -o pr.o pr.c And I got: pr.c: In function `bad': pr.c:11: internal compiler error: in output_325, at insn-output.c:3475 Please submit a full bug report, with preprocessed source if appropriate.
