Bug ID: 103888
Summary: ICE with global register definition after use
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: accepts-invalid, ice-on-invalid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
The following should be rejected but currently is not:
extern long unsigned int sub_0 ( const char * ) ;
extern void * sub_1 ( long unsigned int ) ;
extern int var_0 ;
void * var_1 = & var_0 ;
register int var_0 asm ( "%ecx" ) ;
---- CUT ----
This is similar to PR 93160 for the C++ front-end since the front-ends don't
share merge_decl sources I thought it would be best if we had two bug reports.
