Bug ID: 98693
Summary: Compiling with -mcmodel=large emits .eh_frame with
R_X86_64_PC32
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: chorman64 at gmail dot com
Target Milestone: ---
I am attempting to use gcc to build an operating system for x86_64. I recently
reconfigured it to use the higher half of memory so that OS routines may be
preserved in userspace maps. However, when building with gcc using
`-mcmodel=large`, I get relocation overflow errors (from gold) in `.eh_frame`
(which is presumably a synthetic section, as I have written no sections by that
name). The error persists using gcc with lld (though it is reported
differently, and reports the relocation).
The same issue does not occur when building with the same flags using clang
with lld.
