Subject: [PATCH RESEND] gen-insn-attr-x86.awk: Fix regexp warnings
Date: Tue, 24 Sep 2019 07:46:59 +0300 [thread overview]
Message-ID: <20190924044659.3785-1-alexander.kapshuk@gmail.com> (raw)
In-Reply-To: <20190923114904.dd63949b3433376aeb4b7789@kernel.org>
gawk 5.0.1 generates the regexp warnings shown below:
GEN /home/sasha/torvalds/tools/objtool/arch/x86/lib/inat-tables.c
awk: ../arch/x86/tools/gen-insn-attr-x86.awk:260: warning: regexp escape sequence `\:' is not a known regexp operator
awk: ../arch/x86/tools/gen-insn-attr-x86.awk:350: (FILENAME=../arch/x86/lib/x86-opcode-map.txt FNR=41) warning: regexp escape sequence `\&' is not a known regexp operator
Ealier versions of gawk are not known to generate these warnings.
The gawk manual referenced below does not list characters ':' and '&'
as needing escaping, so 'unescape' them.
https://www.gnu.org/software/gawk/manual/html_node/Escape-Sequences.html
Running diff on the output generated by the script before and after
applying the patch reported no differences.
