add =+label feature, which appends the label to perl-name

Programming / Compilers / PERL - Jim Cromie [gmail.com] - 14 June 2016 20:52 UTC

Using this reduces the burden of keeping each label unique, simplifying the use of labels to name varying workloads created by-Mfoo -M

This enables an invocation like the following to run -DDEBUGGING perls-A,B in bare mode, and heavily encumbered by -Dflag induced overhead:

$] perl Porting/bench.pl --jobs=2 \--tests=/loop::for::my/ \-- \ perl-A=+bare perl-A=+workload -DpsltocPmfr \ perl-B=+bare perl-B=+workload -DpsltocPmfr

Unfortunately, that example falls over, because the -D output upsets cachegrind_parser. That might be fixable by removing the '2>&1' in the $cmd. Nonetheless, workloads are constructible.

more prosaically:

$] perl Porting/bench.pl --jobs=2 \--tests=/loop::for::my/ \-- perl5.18.2=+strict -Mstrict perl5.18.0=+dumper -MData::Dumper

yields:

Got eof for pid 11377 (loop::for::my_array4/perl5.18.0+dumper active/long loop)


loop::for::my_array4 empty for loop with my var and 4 integer array
