* Separate the extraction of hex values.Jarkko Hietaniemi2014-08-171-0/+4
| | | | | | | | | | | | | | | | | | This way we can call it twice: first to count the size of output (and sanity check the extraction indices), and the second time to actually extract. Otherwise with bad extraction code we will smash the stack. Furthermore, this makes for cleaner code since the large #ifdef forest (about differing long double formats, and different uv/nv/quad sizes) is moved within the helper function. Furthermore: IEEE 754 128-bit extraction was extracting wrong: we need only the mantissa bits, and in the right nybble order. Last but not least, handle the 'implicit bit' of IEEE 754 quadruple and double-double (but which is explicitly *not* in the 80-bit format). (If we handled the standard 64-bit format by explicit byte extraction, instead of frexp+ldexp the hidden bit would be needed there, too.)

* Hexadecimal float literals, for perl #122219Jarkko Hietaniemi2014-08-132-0/+25
| | | | | | | | | Do not use system strtod/strtold since its C99 (which we do not require). If we can fit the mantissa bits of a NV to a UV (which is the case for the most common format, 64-bit IEEE 754 double, which has 52 mantissa bits) we will use that, and only in the end convert to NV. If we cannot fit the bits, accumulate the bits incrementally to a NV.
* Hexadecimal float sprintf, for perl #122219Jarkko Hietaniemi2014-08-132-1/+18
| | | | | | | | | | | | | | | | | | Do not use the system sprintf since %a/%A is C99 (which we do not require), and even if we did, there is room for interpretation (for example whether to print trailing zeros or not) which means that existing implementations will inevitably differ. For the most common case, 64-bit doubles of IEEE 754, use first frexp to extract the exponent, and then ldexp to scale the result to a 64-bit unsigned integer. For long doubles (80-bit or 128-bit) we look directly at the mantissa (also known as fraction, or significand) bytes, and their 4-bit nybbles, and extract them in correct order. Since we bypass system printf, we need to do our own aligning, filling, rounding, and other printf logic.

* Reverse order of environ tables under bash on VMS.Craig A. Berry2014-08-081-24/+19
| | | | | | | | | | | | | The default for populating %ENV on VMS is from logical names first and the CRTL environ array second unless overridden by setting PERL_ENV_TABLES. That's a reasonable default for DCL, but not quite right when running under bash as exports under bash might end up hidden behind logical names. So reverse the default order when GNV$UNIX_SHELL is set. Also stop mentioning that setenv() may not be present in the CRTL since it is present for VMS versions 7.0 and later and those are the only ones we support.

* make "require" handle no argument more gracefully, and add testsYves Orton2014-07-301-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in Perl 5.14 the following segfaults: *CORE::GLOBAL::require = sub { }; eval "require"; in Perl 5.18 perl -wle'eval "require";' produces a spurious warning: Use of uninitialized value $_ in require at (eval 1) line 1. In other perls: perl -e 'eval q/require $this/ or print $@' produces: Null filename used at (eval 1) line 1. The error message is crappy, totally unfit for a perl audience, and the spurious warning is just confusing. There is no $_ in use here, why do we warn about it. It looks like 9e3fb20c fixed the segfault (by accident), and also somehow meant that the "Null filename" error would not ever be produced. So this patch ditches the crappy error and replaces it with something meaningful and informative, and tests that we do not regress and start segfaulting again.

* add op_lastsib and -DPERL_OP_PARENTDavid Mitchell2014-07-081-2/+21
| | | | | | | | | | | | | | | | | | | | Add the boolean field op_lastsib to OPs. Within the core, this is set on the last op in an op_sibling chain (so it is synonymous with op_sibling being null). By default, its value is set but not used. In addition, add a new build define (not yet enabled by default), -DPERL_OP_PARENT, that forces the core to use op_lastsib to detect the last op in a sibling chain, rather than op_sibling being NULL. This frees up the last op_sibling pointer in the chain, which rather than being set to NULL, is now set to point back to the parent of the sibling chain (if any). This commit also adds a C-level op_parent() function and B parent() method; under default builds they just return NULL, under PERL_OP_PARENT they return the parent of the current op. Collectively this provides a facility not previously available from B:: nor C, of being able to follow an op tree up as well as down.

| | | | | | | The build process creates a symlink pod/perl$platform.pod pointing to README.$platform for each relevant platform, and we therefore want Git to ignore those generated symlinks. Where we no longer support a given platform, there's no need to have a gitignore entry for it.
