Subject: [PATCH] Fix building on x86_64 with binutils 2.41
|
||
|
|
|
||
|
|
Newer versions of the GNU assembler (observed with binutils 2.41) will
|
||
|
|
complain about the ".arch i386" in files assembled with "as --64",
|
||
|
|
with the message "Error: 64bit mode not supported on 'i386'".
|
||
|
|
|
||
|
|
Fix by moving ".arch i386" below the relevant ".code32" directive, so
|
||
|
|
that the assembler is no longer expecting 64-bit instructions to be used
|
||
|
|
by the time that the ".arch i386" directive is encountered.
|
||
|
|
|
||
|
|
Based on similar iPXE fix:
