Bug ID: 384727
Summary: valgrind does not support debug info for read only
segments (generated by LLD)
Product: valgrind
Version: 3.14 SVN
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: ori...@gmx.fr
Target Milestone: ---
By default (without --no-rosegment option) LLD [1] puts read only code in read
only segments (and provides debug info for it). However, valgrind fails to
parse ELF files that contain debug info for read only segments.
Here is an incomplete attempt to fix this: [2]
It parses read only segments, but then fails to match them with read only
sections at [3]
