* ExtUtils::Constant: Remove impediment to compiling under C++11Karl Williamson2017-08-081-3/+4
| | | | | | | | | | | | | | | | | C++11 changed from earlier versions to require space between the end of a string literal and a macro, so that a feature can unambiguously be added to the language. Starting in g++ 6.2, the compiler emits a deprecation warning when there isn't a space (presumably so that future versions can support C++11). This commit fixes ExtUtils::Constant This patch also changes any affected lines that exceed 79 columns, as specified by perlhack. Code and modules included with the Perl core need to be compilable using C++. This is so that perl can be embedded in C++ programs. (Actually, only the hdr files need to be so compilable, but it would be hard to test that just the hdrs are compilable.) So we need to accommodate changes to the C++ language.
* ExtUtils::Constant - better machine code on threaded perlDaniel Dragan2017-08-081-10/+8
| | | | | | | | | | croak doesnt require a context param to be pushed on the c stack, Perl_croak does, since Perl_croak/croak is very rarily called, minimize the machine code of the error branches don't do dTHX in thread aware XS code, this just sets up another my_perl var for the scope of const-xs BOOT sum masking the original declared my_perl in the outer C scope
* Typo fixes.Nicholas Clark2017-08-082-5/+6
| | | | | Spotted by dsteinbrunner@pobox.com, reported as CPAN #85527. However, I think that the "to to" should be "to do", not "to".
* Avoid compiler warnings due to mismatched types in *printf format strings.Robin Barker2017-08-081-3/+4
| | | | | | | | gcc (and probably others) was warning about a mismatch for between `int` (implied by the format %d) and the actual type passed, `line_t`. Avoid this by explicitly casting to UV, and using UVuf. CPAN #63832
* Refactor ExtUtils::Constant::Utils backwards compatibility code.Nicholas Clark2010-12-171-16/+20
| | | | | Avoid warnings from letting 5.005 even think about POSIX charclass constants in regexps, and use compile-time constants to enable backcompat features.
* For PROXYSUBS, tables may sometimes have no entries.Jan Dubois2010-10-251-4/+6
| | | | | | | | | The reason being that all entries in the tables are guarded with #ifdef, so if none of the symbols are defined, then we still end up with an empty table. This actually happens in the POSIX module on Windows for the "yes" table. This reverts commit c553cca0 and changes based on it.
* use compatible types in a conditional expressionTony Cook2010-10-251-1/+1
| | | | | With some compilers NULL is ((void *)0) which isn't type compatible with the integer returned by hv_exists_ent().
* For PROXYSUBS, add an option to push all constants' names onto an array.Nicholas Clark2010-10-231-13/+47
| | | | | Typically this would be 'EXPORT_OK', to add all constants to the @EXPORT_OK array for this package.
* For PROXYSUBS, allow an explicit XS_SUBNAME of undef to suppress its generation.Nicholas Clark2010-10-231-4/+7
|
* For PROXYSUBS, also avoid calling get_missing_hash() in the XS constant code.Nicholas Clark2010-10-231-4/+16
| | | | | | (Follow on from 4639bd9c727433ad) For modules such as File::Glob and I18N::Langinfo, which always define all constants on all platforms, this saves about 700 bytes of object code.
* For PROXYSUBS, get the hash from the fetch to pass to the subsequent store.Nicholas Clark2010-10-221-8/+17
| | | | This saves the store having to (re)compute the hash.
* For PROXYSUBS, loop with do {} not while, as there is always at least 1 entry.Nicholas Clark2010-10-221-3/+2
|
* For PROXYSUBS, avoid calling get_missing_hash() if all symbols are present.Nicholas Clark2010-10-221-61/+56
| | | | | | | For modules such as File::Glob and I18N::Langinfo, which always define all constants on all platforms, this saves about 1K of object code, plus 1 (empty) anonymous hash (per process or thread) in %ExtUtils::Constant::ProxySubs::Missing.
* For PROXYSUBS, give the notfound struct file scope.Nicholas Clark2010-10-221-8/+11
| | | | All others remain within the scope of the BOOT block.
* Minor refactor of ExtUtils::Constant::ProxySubs.Nicholas Clark2010-10-221-4/+5
| | | | | | Use a lexical in place of repeated lc()'s in WriteConstants. Require ExtUtils::Constant::ProxySubs early, to avoid leaving empty files if it fails for any reason.
* For PROXYSUBS error messages, generate more efficient code for -Uusethreads.Nicholas Clark2010-10-211-4/+21

* Add an option autoload to PROXYSUBS, to generate an AUTOLOAD subroutine.Nicholas Clark2010-10-211-7/+25
| | | | | | | | | Like croak_on_error, this is only useful with the Proxy Constant Subroutine code, as that adds all known constants to the symbol table at compile time. The (obvious) additional restriction is that directly implementing AUTOLOAD is only useful if the package wishes to perform no other autoloading, and to treat all autoload requests as (failed) constant lookups (with errors describing them as such).
* Add option croak_on_error to PROXYSUBS, to directly croak() the error message.Nicholas Clark2010-10-211-3/+37
| | | | | | | This is only useful with the code that generates Proxy Constant Subroutines, as this adds all known constants to the symbol table at compile time, meaning that the only calls to AUTOLOAD will be to load constants not available on this platform, or for invalid constant names.
* Remove unused variable len from code generated by ExtUtils::Constant::ProxySubsNicholas Clark2010-10-191-2/+0
| | | | This was missed from change 575f055216d48b9f.
* Improve the generated C code for $xs_subname for Proxy Constant Subroutines.Nicholas Clark2010-10-191-5/+4
|
* Add missing newline to macro_to_ifndef in ExtUtils::Constant::BaseJerry D. Hedden2010-09-221-1/+1
|
* ExtUtils::Constant::ProxySubs should use mro_method_changed_in() if available.Nicholas Clark2010-09-211-1/+10
|
* Add macro_to_ifndef to ExtUtils::Constant::Base, and use it in place of #elseNicholas Clark2010-09-212-4/+17
| | | | | Previously the code was using the #ifdef generated by macro_to_ifdef(), and immediately following that with an #else. That was ugly. And longer.
* Tweak ExtUtils::Constant::ProxySubs to use hv_exists_ent().Nicholas Clark2010-09-211-3/+2
| | | | | Previously it was using hv_exists(), requiring extra code to unpack the SV and convert it to the correct string form for the hash API.
* Move ExtUtils::Constant from ext/ to cpan/Nicholas Clark2009-10-024-0/+1945
