Docs for TARG / targ

aufflick has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

I've looked before for useful docs on TARG / targ / op_targ / TARGET etc. and when/how it can be set so as to use the more efficient POP* functions among other things.

I had never found anything written about it until I stumbled across this fairly useful post on the perl.perl5.porters news group:

Re: Tantalized by TARG (Was: (patch) Cwd.xs optimizations/abstraction)]

Can anyone suggest any other useful docs/discussions on TARG?

PS: If you have no idea what I'm talking about, TARG is an XS thing :)

I'd be surprised if a non-public-not-for-general-use internal implementation bits were documented, esp when so much of the public-for-general-use bits are under documented http://perldoc.perl.org/perlguts.html#Putting-a-C-value-on-Perl-stack http://search.cpan.org/dist/illguts/index.html http://perl5.git.perl.org/perl.git?a=search&h=HEAD&st=grep&s=define%20XPUSHi http://perl5.git.perl.org/perl.git/blob?f=pp.h#l302 `#define XPUSHi(i) STMT_START { sv_setiv(TARG, (IV)(i)); XPUSHTARG; } STMT_END` http://perl5.git.perl.org/perl.git?a=search&h=HEAD&st=grep&s=define%20STMT_START `# define STMT_START (void)( /* gcc supports "({ STATEMENTS; })" */`	[reply] [d/l] [select]

You can find all the stack manipulation macros in pp.h.	[reply]
