[Bug c++/94835] ICE in vague_linkage_p, at cp/decl2.c:2041
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94835 Stephen Casner changed: What|Removed |Added Resolution|--- |INVALID Status|UNCONFIRMED |RESOLVED --- Comment #5 from Stephen Casner --- This ICE occurred because my additions to config.gcc were incomplete. Those additions did not include elfos.h for pdp11-elf32 so SUPPORTS_ONE_ONLY==0 and TARGET_SUPPORTS_WEAK==0 which caused have_weak==false which caused comdat_linkage() to set TREE_PUBLIC(decl)=0, resulting in the assert failure. This was probably not a supported configuration for compiling C++ code.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94835 --- Comment #4 from Stephen Casner --- I verified that the compilation of chrono:544 is the first time in the build that the failing assert is executed, so that likely implies that the problem is general and not specific to the particular source code. The only mentions of COMDAT in the pdp11 backend are the macros #define TARGET_CXX_CLASS_DATA_ALWAYS_COMDAT hook_bool_void_false #define TARGET_CXX_LIBRARY_RTTI_COMDAT hook_bool_void_false These are in the direction that make the assert true rather than false, so changing those to the default hook_bool_void_true wouldn't help (and would presumably cause something else to fail). I'm way out of my league here, so any suggestions would be appreciated.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94835 --- Comment #3 from Stephen Casner --- I'm working with unmodified gcc sources, but if no other targets are seeing this problem then it may be caused by pdp11-specific code somewhere else. I guess that g++ and libstdc++v3 have never been successfully built for pdp11. Any suggestions for debugging this? Perhaps backing off on some compiler feature that might be tickling the bug?
