Subject: Use tcp->qual_flg instead of qual_flags[] in verbose() and abbrev()
X-Git-Tag: v4.8~128
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=40d63b9a92e049986fce1fb91cca10fdd3d3a64a;p=strace

Use tcp->qual_flg instead of qual_flags[] in verbose() and abbrev()

We have hundreds of uses of these macros.
Result is more efficient and 1.1 kbyte shorter code:

  text	   data	    bss	    dec	    hex	filename
245579	    700	  12928	 259207	  3f487	strace.t5/strace
244471	    700	  12928	 258099	  3f033	strace.t6/strace
