5603 * Hence no surrogates nor non-characters, nor non-Unicode. Thus, if the input
5604 * passes this dfa, it will be for a well-formed, non-problematic code point
5605 * that can be returned immediately.
5607 * The "Implementation details" portion of
5608 * http://bjoern.hoehrmann.de/utf-8/decoder/dfa/ shows how
5609 * the first portion of the table maps each possible byte into a character
5610 * class. And that the classes for those bytes which are start bytes have been
5611 * carefully chosen so they serve as well to be used as a shift value to mask
5612 * off the leading 1 bits of the start byte. Unfortunately the addition of
5613 * being able to distinguish non-characters makes this not fully work. This is
5614 * because, now, the start bytes E1-EF have to be broken into 3 classes instead
5616 * 1) ED because it could be a surrogate
5617 * 2) EF because it could be a non-character
5618 * 3) the rest, which can never evaluate to a problematic code point.
5620 * Each of E1-EF has three leading 1 bits, then a 0. That means we could use a
5621 * shift (and hence class number) of either 3 or 4 to get a mask that works.
5622 * But that only allows two categories, and we need three. khw made the
5623 * decision to therefore treat the ED start byte as an error, so that the dfa
5624 * drops out immediately for that. In the dfa, classes 3 and 4 are used to
5625 * distinguish EF vs the rest. Then special code is used to deal with ED,
5626 * that's executed only when the dfa drops out. The code points started by ED
5627 * are half surrogates, and half hangul syllables. This means that 2048 of the
5628 * the hangul syllables (about 18%) take longer than all other non-problematic
5629 * code points to handle.
5631 * The changes to handle non-characters requires the addition of states and
5632 * classes to the dfa. (See the section on "Mapping bytes to character

6251 This macro should be used as a statement. It declares a private variable
6252 (whose name begins with an underscore) that is needed by the other macros in
6253 this section. Failing to include this correctly should lead to a syntax error.
6254 For compatibility with C89 C compilers it should be placed in a block before
6255 any executable statements.
6257 =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING
6259 This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the
6260 locale for category C<LC_NUMERIC> to be what perl thinks is the current
6261 underlying locale. (The perl interpreter could be wrong about what the
6262 underlying locale actually is if some C or XS code has called the C library
6263 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling
6264 this macro will update perl's records.)
6266 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6267 declare at compile time a private variable used by this macro. This macro
6268 should be called as a single statement, not an expression, but with an empty
6269 argument list, like this:
6272 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6274 STORE_LC_NUMERIC_FORCE_TO_UNDERLYING();
6276 RESTORE_LC_NUMERIC();
6280 The private variable is used to save the current locale state, so
6281 that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it.
6283 On threaded perls not operating with thread-safe functionality, this macro uses
6284 a mutex to force a critical section. Therefore the matching RESTORE should be
6285 close by, and guaranteed to be called.
6287 =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED
6289 This is used to help wrap XS or C code that is C<LC_NUMERIC> locale-aware.
6290 This locale category is generally kept set to a locale where the decimal radix
6291 character is a dot, and the separator between groups of digits is empty. This
6292 is because most XS code that reads floating point numbers is expecting them to
6295 This macro makes sure the current C<LC_NUMERIC> state is set properly, to be
6296 aware of locale if the call to the XS or C code from the Perl program is
6297 from within the scope of a S<C<use locale>>; or to ignore locale if the call is
6298 instead from outside such scope.
6300 This macro is the start of wrapping the C or XS code; the wrap ending is done
6301 by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise
6302 the state can be changed that will adversely affect other XS code.
6304 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6305 declare at compile time a private variable used by this macro. This macro
6306 should be called as a single statement, not an expression, but with an empty
6307 argument list, like this:
6310 DECLARATION_FOR_LC_NUMERIC_MANIPULATION;
6312 STORE_LC_NUMERIC_SET_TO_NEEDED();
6314 RESTORE_LC_NUMERIC();
6318 On threaded perls not operating with thread-safe functionality, this macro uses
6319 a mutex to force a critical section. Therefore the matching RESTORE should be
6320 close by, and guaranteed to be called.
6322 =for apidoc Am|void|RESTORE_LC_NUMERIC
6324 This is used in conjunction with one of the macros
6325 L</STORE_LC_NUMERIC_SET_TO_NEEDED>
6326 and L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING> to properly restore the
6327 C<LC_NUMERIC> state.
6329 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to
6330 declare at compile time a private variable used by this macro and the two
6331 C<STORE> ones. This macro should be called as a single statement, not an
6332 expression, but with an empty argument list, like this:

6637 * 2. Declare a typedef named my_cxt_t that is a structure that contains
6638 * all the data that needs to be interpreter-local.

7260 * To back up a bit (harhar):
7262 * For IEEE 754 64-bit formats [1]:
7264 * s 000 (mantissa all-zero) zero
7265 * s 000 (mantissa non-zero) subnormals (denormals)
7266 * s 001 ... 7fe normals
7269 * For IEEE 754 128-bit formats:
7271 * s 0000 (mantissa all-zero) zero
7272 * s 0000 (mantissa non-zero) subnormals (denormals)
7273 * s 0001 ... 7ffe normals
7276 * [1] this looks like big-endian, but applies equally to little-endian.
7278 * s = Sign bit. Yes, zeros and nans can have negative sign,
7279 * the interpretation is application-specific.
7281 * q = Quietness bit, the interpretation is platform-specific.
7282 * Most platforms have the most significant bit being one
7283 * meaning quiet, but some (older mips, hppa) have the msb
7284 * being one meaning signaling. Note that the above means
7285 * that on most platforms there cannot be signaling nan with
7286 * zero payload because that is identical with infinity;
7287 * while conversely on older mips/hppa there cannot be a quiet nan
7288 * because that is identical with infinity.
7290 * Moreover, whether there is any behavioral difference
7291 * between quiet and signaling NaNs, depends on the platform.
7293 * x86 80-bit extended precision is different, the mantissa bits:
7295 * 63 62 61 30387+ pre-387 visual c
7296 * -------- ---- -------- --------
7297 * 0 0 0 invalid infinity
7298 * 0 0 1 invalid snan
7299 * 0 1 0 invalid snan
7300 * 0 1 1 invalid snan
7301 * 1 0 0 infinity snan 1.#INF
7302 * 1 0 1 snan 1.#SNAN
7303 * 1 1 0 qnan -1.#IND (x86 chooses this to negative)
7304 * 1 1 1 qnan 1.#QNAN
7306 * This means that in this format there are 61 bits available
7307 * for the nan payload.
7309 * Note that the 32-bit x86 ABI cannot do signaling nans: the x87
7310 * simply cannot preserve the bit. You can either use the 80-bit
7311 * extended precision (long double, -Duselongdouble), or use x86-64.
7313 * In all platforms, the payload bytes (and bits, some of them are
7314 * often in a partial byte) themselves can be either all zero (x86),
7315 * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double
7316 * or in a double-double, the first half of the payload can follow the
7317 * native double, while in the second half the payload can be all
7318 * zeros. (Therefore the mask for payload bits is not necessarily
7319 * identical to bit complement of the NaN.) Another way of putting
7320 * this: the payload for the default NaN might not be zero.
7322 * For the x86 80-bit long doubles, the trailing bytes (the 80 bits
7323 * being 'packaged' in either 12 or 16 bytes) can be whatever random
7326 * Furthermore, the semantics of the sign bit on NaNs are platform-specific.
7327 * On normal floats, the sign bit being on means negative. But this may,
7328 * or may not, be reverted on NaNs: in other words, the default NaN might
7329 * have the sign bit on, and therefore look like negative if you look
7330 * at it at the bit level.
7332 * NaN payloads are not propagated even on copies, or in arithmetics.
7333 * They *might* be, according to some rules, on your particular
7334 * cpu/os/compiler/libraries, but no guarantees.
7336 * To summarize, on most platforms, and for 64-bit doubles
7337 * (using big-endian ordering here):
7339 * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet
7340 * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet
7341 * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling
7342 * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling
7344 * The C99 nan() is supposed to generate *quiet* NaNs.
7346 * Note the asymmetry:
7347 * The 7FF0000000000000 is positive infinity,
7348 * the FFF0000000000000 is negative infinity.
7351 /* NVMANTBITS is the number of _real_ mantissa bits in an NV.
7352 * For the standard IEEE 754 fp this number is usually one less that
7353 * *DBL_MANT_DIG because of the implicit (aka hidden) bit, which isn't
7354 * real. For the 80-bit extended precision formats (x86*), the number
7355 * of mantissa bits... depends. For normal floats, it's 64. But for
7356 * the inf/nan, it's different (zero for inf, 61 for nan).
7357 * NVMANTBITS works for normal floats. */
