Subject: LD/PE: Make arch identifiers enumeration constants
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=68d466101405e0660eb9619b8aaba7b2b5fec8a3;p=thirdparty%2Fbinutils-gdb.git

LD/PE: Make arch identifiers enumeration constants

Convert internal PE architecture identifiers from macros to enumeration
constants so as to make any further updates less disruptive to code.

Add a PE_ARCH_none dummy placeholder so as to start the numbering of
actual architectures from 1 without the need to specify the numeric
value for any of the constants.

No functional change.  Suggested by Richard Earnshaw.
