Bug ID: 88188
Summary: ICE in print_operand, at config/rs6000/rs6000.c
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: asolokha at gmx dot com
Target Milestone: ---
Target: powerpc-*-linux-gnu, powerpcspe-*-linux-gnu
rs6000 and powerpcspe backends ICE processing some kinds of invalid assembly.
Namely, they hit gcc_unreachable() or gcc_assert() compiling
gcc/testsuite/gcc.target/i386/indirect-thunk-register-4.c,
gcc/testsuite/gcc.target/cris/20011127-1.c, and
gcc/testsuite/gcc.target/msp430/msp_abi_div_funcs.c:
% powerpc-e300c3-linux-gnu-gcc-9.0.0-alpha20181118 -c
gcc/testsuite/gcc.target/i386/indirect-thunk-register-4.c
during RTL pass: final
gcc/testsuite/gcc.target/i386/indirect-thunk-register-4.c: In function 'foo':
gcc/testsuite/gcc.target/i386/indirect-thunk-register-4.c:10:1: internal
