Bug ID: 102988
Summary: ice during GIMPLE pass: hardcbr
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
Created attachment 51694
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51694&action=edit
gzipped C++ source code
The attached C++ code, with compiler flags -c -w -std=c++14 -w -O1
-fharden-conditional-branches, does this:
/home/dcb35/rpmbuild/BUILD/ucommon-7.0.0/commoncpp/persist.cpp:254:19: error:
RESULT_DECL should be read only when DECL_BY_REFERENCE is set
254 | const std::string PersistEngine::readClass() throw(PersistException)
| ^~~~~~~~~~~~~
while verifying SSA_NAME className_96 in statement
__asm__("" : "=g" className_96 : "0" className_14(D));
during GIMPLE pass: hardcbr
/home/dcb35/rpmbuild/BUILD/ucommon-7.0.0/commoncpp/persist.cpp:254:19: internal
compiler error: verify_ssa failed
I will have my usual go at reducing the code.
