Remove i386_elf_emit_arch_note
This x86 assembler patch:
https://sourceware.org/ml/binutils/2001-11/msg00344.html
generates a .note section for .arch directive so that GDB can tell which
architecture an i386 binary belongs:
https://sourceware.org/ml/binutils/2001-11/msg00271.html
However, x86 assembly code can have any instructions. A .note section
doesn't help. This patch removes it.
gas/
* config/tc-i386.c (i386_elf_emit_arch_note): Removed.
* config/tc-i386.h (md_end): Likewise.
(i386_elf_emit_arch_note): Likewise.
gas/testsuite/
* gas/i386/i386.exp: Run note.
* gas/i386/note.d: New file.
* gas/i386/note.s: Likewise.
