Subject: [PATCH 16/51] linker/lld: do not generate quoted section names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
LLVM LD doesn't strip the quotes from the section names, and so the
resulting binary ends up with section names like:
[ 1] ".text" PROGBITS ffff82d040200000 00008000
000000000018cbc1 0000000000000000 AX 0 0 4096
This confuses some tools (like gdb) and prevents proper parsing of the
binary.
The issue has already been reported and is being fixed in LLD. In
order to workaround this issue and keep the GNU ld support define
different DECL_SECTION macros depending on the used ld
implementation.
Drop the quotes from the definitions of the debug sections in
DECL_DEBUG{2}, as those quotes are not required for GNU ld either.
Fixes: 6254920587c3 ('x86: quote section names when defining them in linker script')
