[perl script] print the assembly instruction and count the occurence
Hi,

I have a input file(text file) with the following lines.

Code:
0x000000 0x5a80 0x0060 BRA.l 0x60 ;file:UserCall.s ;function:_user_call_table ;C_sourceLine:24
0x000002 0x1bc5 RETI ;file:UserCall.s ;function:_user_call_table ;C_sourceLine:30
0x000003 0x6840 MOV R0L,R0L ;file:UserCall.s ;function:_user_call_table ;C_sourceLine:31
0x000004 0x1bc5 RETI ;file:UserCall.s ;function:_user_call_table ;C_sourceLine:35
0x000005 0x6840 MOV R0L,R0L ;file:UserCall.s ;function:_user_call_table ;C_sourceLine:36

Expected output is some thing like this :

Code:
BRA.l 0x60
RETI
MOV R0L,R0L
RETI
MOV R0L,R0L


and it should count the occurence too like
MOV R0L,R0L occured 2 times
RETI occured 1
BRA.l 0x60 occured 1

So far I have developed code and need help here

Code:
#!/usr/local/bin/perl -w


my $filename = 'C:\data1.txt';
my @opcode_var = 0;
my @s_words = 0;
my $fun_name = 0;
my $file_name = 0;
my $output_var = 0;
my $remove_hex = 0;
open(FILE,$filename) or die "Could not read from filename";
my @lines = <FILE>;
chop @lines;
my $word = 0;

foreach my $line(@lines) 
{
	if ($line =~ /0x*/)
	{
		chop ($line);
		@opcode_var = split(/ /,$line);
		if($opcode_var[2] =~ /0x*/)
		{
			print "$opcode_var[3] $opcode_var[4]\n";
		}
		else
		{
			if($opcode_var[2] =~ /0x*/)
			{
				print "$opcode_var[2] $opcode_var[3]\n";
			}
		}
	}
}

you can copy this code and print the output. Just stuck here. Learning to extract the assembly code from .s file.

Thank you.

any help is appreciated.

locale::codes::langext

Locale::Codes::LangExt(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangExt(3pm)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
