Subject: [RFA] Fix inconsistency in blockvector addrmap vs non-addrmap handling
|
||||
|
||||
Hi.
|
||||
|
||||
I was seeing the assert in dw2_find_pc_sect_psymtab trigger
|
||||
and traced it to the fact that when pending_addrmap_interesting gets
|
||||
set blockvector.map is used instead of blockvector.block.
|
||||
The difference is that blockvector.block contains entries for the global
|
||||
and static blocks whereas pending_addrmap doesn't.
|
||||
|
||||
This patch fixes this by making them consistent.
|
||||
I suspect more work is necessary (e.g. can symtabs "overlap" even though
|
||||
the individual pieces do not?).
|
||||
But I first want to fix the regression introduced by the change
|
||||
to dw2_find_pc_sect_psymtab: There is more code in a symtab than is
|
||||
documented by function and lexical block pc ranges (e.g. C++ method thunks).
|
||||
|
||||
Regression tested on amd64-linux, and by verifying the assert no longer
|
||||
triggers in the testcase I was using.
|
||||
|
||||
Ok to commit?
