Bug ID: 29648
Summary: Static-pie builds contain many redundant GOT
references
Product: glibc
Version: 2.35
Status: NEW
Severity: normal
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: wdijkstr at arm dot com
CC: carlos at redhat dot com
Target Milestone: ---
The static-pie changes introduced ~1200 unnecessary GOT references in the
lib/*.a files. Even --disable-default-pie results in ~288 GOT references. GLIBC
2.34 and earlier contain zero GOT accesses as expected.
One issue is that "hidden" attributes are ignored with static-pie, which
results in codequality of the static-pie build being worse than fPIC...

--- Comment #1 from Andreas Schwab <schwab@linux-m68k.org> ---
What does lib/*.a refer to?

> What does lib/*.a refer to?
libc.a and libm.a are the 2 main ones, but there are a few smaller ones in the
install directory.
