--- Comment #4 from jgreenhalgh at gcc dot gnu.org --- Created attachment 30293 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30293&action=edit Less reduced failing testcase Yes, the same thing happens for packed versions of those structs. Perhaps the attached, less-reduced, version of the testcase will make the issue more clear. This expanded testcase fails with the same error and ICE: ../build-arm-none-eabi/install/bin/arm-none-eabi-gcc ../testcases/pr-less-reduced.c -O1 -Wall ../testcases/pr-less-reduced.c: In function 'inet_rtm_getroute': ../testcases/pr-less-reduced.c:22:3: error: output number 0 not directly addressable __asm__ __volatile__("" ^ ../testcases/pr-less-reduced.c:22:3: internal compiler error: in expand_asm_operands, at stmt.c:910 0x8c1be8 expand_asm_operands /work/oban-dev/src/gcc/gcc/stmt.c:910 0x8c28a7 expand_asm_stmt(gimple_statement_d*) /work/oban-dev/src/gcc/gcc/stmt.c:1151 0x5dfe5f expand_gimple_stmt_1 /work/oban-dev/src/gcc/gcc/cfgexpand.c:2154 0x5dfe5f expand_gimple_stmt /work/oban-dev/src/gcc/gcc/cfgexpand.c:2309 0x5e1b69 expand_gimple_basic_block /work/oban-dev/src/gcc/gcc/cfgexpand.c:4143 0x5e4a33 gimple_expand_cfg /work/oban-dev/src/gcc/gcc/cfgexpand.c:4662 Please submit a full bug report, with preprocessed source if appropriate.
