For consistency, allow local labels in all similar full-line conversions as well. --- gas-preprocessor.pl | 19 ++++++++++--------- 1 file changed, 10 insertions(+), 9 deletions(-) diff --git a/gas-preprocessor.pl b/gas-preprocessor.pl index a8cf1e0..6353a07 100755 --- a/gas-preprocessor.pl +++ b/gas-preprocessor.pl @@ -793,24 +793,25 @@ sub handle_serialized_line { if ($arch eq "aarch64") { # fix missing aarch64 instructions in Xcode 5.1 (beta3) # mov with vector arguments is not supported, use alias orr instead - if ($line =~ /^\s*mov\s+(v\d[\.{}\[\]\w]+),\s*(v\d[\.{}\[\]\w]+)\b\s*$/) { - $line = " orr $1, $2, $2\n"; + if ($line =~ /^(\d+:)?\s*mov\s+(v\d[\.{}\[\]\w]+),\s*(v\d[\.{}\[\]\w]+)\b\s*$/) { + $line = "$1 orr $2, $3, $3\n"; } # movi 16, 32 bit shifted variant, shift is optional - if ($line =~ /^\s*movi\s+(v[0-3]?\d\.(?:2|4|8)[hsHS])\s*,\s*(#\w+)\b\s*$/) { - $line = " movi $1, $2, lsl #0\n"; + if ($line =~ /^(\d+:)?\s*movi\s+(v[0-3]?\d\.(?:2|4|8)[hsHS])\s*,\s*(#\w+)\b\s*$/) { + $line = "$1 movi $2, $3, lsl #0\n"; } # Xcode 5 misses the alias uxtl.
