Bug ID: 119766
Summary: -gsplit-dwarf and -fdebug-types-section leads to
multiple .debug_info.dwo sections
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: simon.marchi at polymtl dot ca
Target Milestone: ---
Using the test file:
---
#include <vector>
int main()
{
std::vector<int> foo;
foo.push_back(3);
return foo[0];
}
---
Compiling it with:
$ g++ test.cpp -gsplit-dwarf -fdebug-types-section -g3
leads to many .debug_info.dwo sections:
$ readelf -S a-test.dwo | grep debug_info | wc -l
49
Each type and compile unit is placed in its own section. We would expect to
see a single section with all units concatenated. This is what clang produces:
$ clang++ test.cpp -gsplit-dwarf -fdebug-types-section -g3
readelf -S a-test.dwo | grep debug_info | wc -l
1
That single section contains 19 units.
