Red Hat Bugzilla – Bug 253770
Support for DW_OP_implicit_value operation for location expressions.
Last modified: 2015-03-04 19:10:52 EST
Description of operator from proposal:
The DW_OP_implicit_value operation takes two operands:
an unsigned LEB128 length, followed by a block
representing the value in the native representation of the
target machine. The length operand gives the length in
bytes of the block that follows. This operation should be
used only in location lists for ranges where the value of
a variable does not exist in memory or in a register, but
is known to be constant.
This proposed new operation is not part of the official DWARF standard yet, and
AFAIK no GNU compiler produces it. So this is premature.
Based on the date this bug was created, it appears to have been reported
during the development of Fedora 8. In order to refocus our efforts as
a project we are changing the version of this bug to '8'.
If this bug still exists in rawhide, please change the version back to
(If you're unable to change the bug's version, add a comment to the bug
and someone will change it for you.)
Thanks for your help and we apologize for the interruption.
The process we're following is outlined here:
We will be following the process here:

doesn't happen again.

This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Non-bug til it's a standard op and generated by anything.
