Setting a bit field in a value that has an optimized-out DW_OP_bit_piece gives strange behavior: print a.i = 7 warning: bits 24-32 in computed object were optimized out; replacing with zeroes $8 = <value optimized out> The ideal in this case would be for GDB to notice that only valid bits are being touched, so the value is not considered to be optimized out. -- Summary: setting a bitfield involving an empty DW_OP_bit_piece gives error Product: gdb Version: unknown Status: UNCONFIRMED Severity: normal Priority: P2 Component: exp AssignedTo: unassigned at sourceware dot org ReportedBy: tromey at redhat dot com CC: gdb-prs at sourceware dot org http://sourceware.org/bugzilla/show_bug.cgi?id=11636 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 3+ messages in thread
