* initialize default_inc_excludes_dot to '' like every variableTony Cook2017-03-141-1/+1
| | | | Handling of the default is done further down.
* Turn on removal of dot in @INC by default:Sawyer X2017-03-141-7/+7
| | | | That's it. Dot no longer in @INC.
* (perl #130108) check if dtrace accepts -xnolibs and use it if availableTony Cook2017-01-051-3/+31
| | | | | | | | dtrace without -xnolibs fails in a FreeBSD jail, so we need to supply it on FreeBSD. Unfortunately systemtap's dtrace emulation doesn't support -xnolibs so we need to test if it's available.
* Configure: also zero out high bytes of 80-bit ldnanNiko Tyni2016-11-221-0/+1
| | | | | These are currently zero anyway, but things are probably not guaranteed to stay so.
* Configure: fix garbage filtering with 80-bit long doublesNiko Tyni2016-11-221-8/+6
| | | | | | | | | The test had several problems that resulted in the excess bytes not getting zeroed out. This caused random contents in $Config{longdblinfbytes}, observed on Debian with GCC 6.2.0 (but not 5.4.1). Bug-Debian: https://bugs.debian.org/844752

* Remove "." from default @INC when default_inc_excludes_dot is setH.Merijn Brand2016-11-111-0/+24
| | | | | | | | | | | | | | | | Perl now provides a way to build perl without . in @INC by default. If you want this feature, you can build with -Ddefault_inc_excludes_dot Because the testing / make process for perl modules do not function well with . missing from @INC, Perl now supports the environment variable PERL_USE_UNSAFE_INC=1 which makes Perl behave as it previously did, returning . to @INC in all child processes. WARNING: PERL_USE_UNSAFE_INC has been provided during the perl 5.25 development cycle and is not guaranteed to function in perl 5.26. Update unit tests and default value files to work with the new %Config variable "default_inc_excludes_dot"
* Re-gen after backport with serious fixesH.Merijn Brand2016-11-111-20/+20

* Configure: add defs summarizing doublekind/longdblkindJarkko Hietaniemi2016-10-281-1/+97
| | | | | | | | | | For windows/netware It seems that many of the recent fp definitions have not been yet copied over there [1] [2], so went mostly by dead reckoning [3]. [1] Note that many of them are not absolutely necessary for building. [2] The proper updating involves doing stuff in win32, which I do not have. [3] As far as I can tell, Windows CE does not really not have long double.
* Configure: signbit scan assuming too muchJarkko Hietaniemi2016-10-211-1/+1
| | | | | | | It was assuming a negative zero, which is an IEEE-754 only concept. There is no need to assume the negative zero for the correct functioning of the signbit, however.
* Add scan for IBM and Cray mainframe fp formats.Jarkko Hietaniemi2016-10-171-1/+19
| | | | | | | | | | | For completeness: it's quite unlikely Perl would build in those environments. Though with Cray it's less impossible: Perl used to build in C90 UNICOS, in 5.8-ish timeframe. With IBM, highly unlikely, because there probably never was a UNIXy enough environment where the IBM Floating Point Architecture was used.

* Configure: clarify "version-specific"Dan Collins2016-07-141-4/+7
| | | | | | This has long been a confusing configure question. It sounds like it saves time by installing /less/, but really it just installs binaries with a version number suffix.
* make Configure abort if both -Duselongdouble and -Dusequadmath are requestedTony Cook2016-07-111-0/+14
| | | | See [perl #126203]
* Minor change after backpotinrH.Merijn Brand2016-07-061-1/+1
| | | | The oxford comma makes no sense in a list of just two
* [perl #128538] [PATCH] Fix copy/paste error in ConfigureH.Merijn Brand2016-07-051-1/+1
| | | | Self-explanatory. The code in question adds -quadmath to archname, but only if it isn't already there. However, since this was copied from a few lines earlier, it checks for -ld instead of -quadmath.
* VAX: Configure changes for VAX floatsJarkko Hietaniemi2016-07-011-2/+20
| | | | | | | | | | | | | Detect the VAX floating point formats D and G. And the F float, but that is float (duh), never likely to be the double, but do it for consistency (we detect IEEE single precision floats, too). The T float and X float are the IEEE 64-bit and 128-bit, but those were available only on the Alpha. Tested on vax-netbsd.
* Add Configure probe for strerror_l()Aaron Crane2016-06-021-0/+6
| | | | | | | | | As requested by khw++ Until the relevant symbol is used, HAS_STRERROR_L must be mentioned explicitly in metaconfig.h. This corresponds to metaconfig d0838744f03cfe7642950ea91dd48f575d0bfd15.
* Add Configure probe for querylocale()Aaron Crane2016-06-021-0/+6
| | | | | | | | | As requested by khw++ Until the relevant symbol is used, HAS_QUERYLOCALE must be mentioned explicitly in metaconfig.h. This corresponds to metaconfig 541f0dd272df4f9326996727898393ac8f6626f7.

* fix symbol detection with gcc 6 link-time optimization (RT #128131)Lukas Mai2016-05-141-2/+2

* Fix the Configure escape with usecrosscompile but no targethostNiko Tyni2016-05-101-1/+1
| | | | | | | | | | | | Commit 97076f2 added a graceful exit to Configure when targethost is not defined but usecrosscompile is. However, this is not reached because there is a similar check a bit earlier that makes Configure bail out. Make the earlier check warn instead of croaking. The use case for this combination is supplying an external config.sh suitable for the target platform, avoiding the need for configuration probes.
* Regenerate Configure and related parts after backportsAaron Crane2016-04-231-10/+28

* Configure: silence 'dtrace -G' probeDavid Mitchell2016-03-181-1/+1
| | | | | | When built with -Dusedtrace, Configure checks to see whether 'dtrace -G' is supported, by running it. If it fails, it may spew error messages to stderr, so use >/dev/null 2>&1.
* Configure: silence some try.c warningsDavid Mitchell2016-03-141-1/+1
| | | | | | | | | On one of the try.c compilations, redirect stderr to /dev/null, since the code can legitimately warn without there being a problem. The try.c in question is probing for what symbols the compiler supports. The clang extensions __has_include and __has_include_next are designed only to be used in .h files, so they warn if used from try.c
* [perl #122287] probe in Configure whether dtrace builds an objectTony Cook2016-03-091-0/+29
| | | | | | | | | | | | | | | | When building the object file, newer versions of dtrace (on Illumos based systems at least) require an input object file that uses at least one of the probes defined in the .d file. The test in Makefile.SH didn't provide that definition so the test would fail, and not build an object file, and fail to link later on, on systems that *do* need the object file. Moved the probe to Configure (where it probably belongs) and supplied an object file that uses a probe. Tested successfully on OmniOS (with the new dtrace), Solaris 11, and darwin.

* Probe for and expose more fields for SA_SIGINFODagfinn Ilmari Mannsåker2016-01-261-0/+67
| | | | | | | | These are all specified by POSIX/SUSv3, but not all platforms have them, as mentioned in POSIX.pm. We can only test the pid, uid and code fields, since they are the only ones that are defined for a user-sent signal.
* Add Configure support for fdclose() for [perl #126847].Andy Dougherty2016-01-041-0/+6
| | | | | This patch also adjusts the generated files suggested by Porting/checkcfgvar.pl.
* Remove nm from libswantedAndreas Koenig2016-01-041-1/+1
| | | | | Nm stood for "New Math" library in the context of 1994. 2014 a conflicting library libnm appeared that has a network manager context.

* Configure: grep -q is not portableJarkko Hietaniemi2015-12-171-1/+1
| | | | It does not work in SysV (solaris) or old BSD greps.
* Configure: infnan for mixed-endian double-doubleJarkko Hietaniemi2015-12-141-3/+11
|
* Configure: mixed-endian double-doublesJarkko Hietaniemi2015-12-141-4/+24
| | | | | | | | | | | The ppc64el is the first seen little-endian double-double (and also the first little-endian ppc), but it turns out its little-endianness is mixed: the doubles are still in big-endian order. Configure was expecting wrongly a fully byte-reversed double-double. Therefore extend the long double format detection to cover all the (double-double) permutations, though the formats of five and eight are rather unlikely (based on current platforms using double-double).
* Configure: cannot trust the bytes after the 80-bit fpJarkko Hietaniemi2015-12-141-3/+4
| | | | They can be zero, they can be garbage.
* Configure: unbreak -S option now that -O is the defaultAaron Crane2015-12-021-1/+1
| | | | | | | | | | | | | | | As far as I can tell, using the -S and -O options together has always yielded an error of this form: Configure: 2042: .: Can't open ./optdef.sh That's because, even though optdef.sh is created in the UU directory, and most of Configure is run in that directory, part of the -S implementation is run in the root directory, and was therefore trying to read ./optdef.sh instead of ./UU/optdef.sh. As of 41d73075f0801c26794dadb1ff690f305d7e53a7, the -O mode is always enabled, so the -S option has been broken since then. This fixes that.

* Try to avoid doubling the cppflags if rerun without removing config.shJarkko Hietaniemi2015-10-161-1/+6
| | | | | | | | | | | This bug has been here since 2001, introduced by yours truly in 58e77565. Hasn't been too harmful, obviously. It doubles the cppflags only once, thankfully, unlimited doubling would probably have been noticed earlier. The avoidance maneuver is far from fool-proof. To be more fooler-proofer, some sort of order-preserving deduping would be needed.
