Bug ID: 108541
Summary: Convert x86 assembly stub to PIC to fix linking with
lld
Product: Mesa
Version: unspecified
Hardware: Other
OS: OpenBSD
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
Assignee: mesa-dev@lists.freedesktop.org

Convert entry_x86_tsd.h to PIC
The x86 assembly language stub in src/mapi/entry_x86_tsd.h does not generate
PIC (position-independent code). This causes text relocations, which are by
default treated as an error by LLVM's lld linker (now used by FreeBSD and
OpenBSD) when building a shared library.
/usr/bin/ld: error: can't create dynamic relocation R_386_32 against symbol:
_glapi_Dispatch in readonly segment; recompile object files with -fPIC
>>> defined in .libs/shared_glapi_libglapi_la-u_current.o
>>> referenced by entry.c
>>> .libs/shared_glapi_libglapi_la-entry.o:(.text+0x1)
The accompanying minimal diff remedies this by generating PIC code. This is
mostly copied from the neighboring entry_x86_tls.h.
