Subject: Perl_sv_vcatpvfn_flags: simplify an expression
X-Git-Tag: v5.27.1~81^2~96
X-Git-Url: https://perl5.git.perl.org/perl5.git/commitdiff_plain/196344c20348c6f1effb9b3dabcee6350d47fbff?hp=c0535913148dc15651cf402b864ceb78a5e40c6d

Perl_sv_vcatpvfn_flags: simplify an expression

In the hex floating/point code, (subnormal ? vfnz : vhex) is equivalent to
v0, which we just set to the same value.

So keep things simple.
