" asmfmt.vim: Vim command to format Go asm files with asmfmt
" (github.com/klauspost/asmfmt).
"
" This filetype plugin adds new commands for asm buffers:
"
" :Fmt
"
" Filter the current asm buffer through asmfmt.
" It tries to preserve cursor position and avoids
" replacing the buffer with stderr output.
"
" Options:
"
" g:go_asmfmt_autosave [default=0]
"
" Flag to automatically call :Fmt when file is saved.
" don't spam the user when Vim is started in Vi compatibility mode
