1b0a41e6cb Add Clang/c2 solution with conversion_test_clang project. Clang/c2 uses the Microsoft rather than GCC intrinsics, so check for defined(_MSC_VER) before defined(__clang__) 2015-12-11 08:15:25 -05:00

f14f080359 Change the specification for native ordering to allow implementations to support orderings in addition to big and little. Thanks to Howard Hinnant for suggesting this change and providing draft wording. Also update headers to reflect actual inclusion hierarchy. 2015-10-16 10:30:34 -04:00

01f7e359bb Update docs to reflect removal of floating point support from 1.58.0 2015-03-25 08:05:49 -04:00
Beman
5caf1d16c8 Remove floating point support for boost 1.58.0. As currently implemented, return by value operations are not reliable because normalization and other bit pattern changes can occur. Docs not updated as yet. Floating point support will be corrected and reinstated for boost 1.59.0, based on in-place customization and inplace and/or copy signatures to replace the unsafe (i.e. native_to_big/little ) by value returns. The big/little_to_native return by value functions are safe, but require reimplementation. 2015-03-24 17:24:56 -04:00

Beman
072b495240 Add Endian specific lightweight_test.hpp with new macro BOOST_TEST_MEMCMP_EQ that uses std::memcmp(...)==0 to determine equality. Bitwise equality is the standard we want floating point round trips to be held to, since NaN's are then equal. 2015-03-05 10:52:28 -05:00

321d5a087a For X86 and X64 architectures, which permit unaligned loads and stores, unaligned little endian buffer and arithmetic types use regular loads and stores when the size is exact. This makes unaligned little endian buffer and arithmetic types significantly more efficient on these architectures.(Pull request from Jeremy Maitin-Shepard) Docs updated, but timing results have not yet been updated. 2015-01-06 16:57:53 -05:00

c201455c84 Change "in_place" to "inplace". Rationale: shortens names without impacting expressiveness. 2014-12-10 09:39:03 -05:00
Beman
2cbcd6f7d3 Rename "runtime_conditional_reverse" to "conditional_reverse". The differing number of arguments is sufficient to disambiguate the compile-time and run-time overloads. 2014-12-10 09:26:47 -05:00

Beman
55a65c3806 Revert to again supply the reverse_endianness_in_place template. This has the effect of providing a default reverse_endianness_in_place for user-defined types. Add error checking for UDT's to verify this works as desired. Provide a note in the conversion docs to that effect. 2014-12-09 11:36:42 -05:00

ce73f59741 Add "_endianness" to the names of the two customization points. These names must be defined in user namespaces (for ADL to work) and so must be much more explicit than names that are defined in namespace endian. 2014-11-23 08:40:58 -05:00
Beman
f9c562b4b4 Rework conversion.hpp: Make the UDT customization point for the value returning conversion functions much more explicit. Provide a separate UDT customization point for the in-place conversion functions, and reverse_in_place() overloads for the built-in arithmetic types. Eliminate the unsafe general-use reverse functions. With explicit customization points these are no longer needed. Complete the renaming of conversion functions started in the prior commit. The reverse and reverse_in_place names are much more meaningful and less likely to be misunderstood. The longer "reverse_in_place" name will hopefully at least slow users down before inappropriate (and possibly unsafe use, such as when trying to recover data after an exception). 2014-11-22 16:27:11 -05:00
Beman
49a91c293a Rename endian_buffer typedefs. New names a bit longer, but also a bit more explicit and more obviously related to endian_arithmetic typedefs. 2014-11-21 15:49:28 -05:00
Beman
84faaa7bbf Rename the conversion functions to discourage unthinking use of the in-place versions as these are unsafe in that they effectively break the type system by treating the buffer as an undescriminated union. Remove the synonym functions based on names popularized by BSD, OS X, and Linux since these are permitted to be implemented as macros, which would cause endless difficulties if encountered. 2014-11-20 15:38:25 -05:00
Beman
fc7733ade1 Major renaming. Class "endian" becomes class "endian_arithmetic" to mimic the C++ standard's description of such types as "arithmetic types". Rename header accordingly. The convenience typedefs have been changed shorten aligned names, as they are often being, but keeping the unaligned type names relatively short via a simple "_ut" suffix. 2014-11-19 10:53:11 -05:00
Beman
61d9046348 Remove "operator value_type() const noexcept" from buffers. Make the buffer ctor explicit. Buffers were requested by people who do not want automatic conversions because they want full control over conversions, and are very concerned about "efficiency". 
Add "operator value_type() const noexcept" to the endian arithmetic types. These types are used by people who do want fully automatic conversions. The arithmetic types need to be drop-in replacements for the built-in arithmetic types for these users.

Beman
d339470e6e Remove "explicit" from Endian type constructors. Rationale: Having to write "cntr.insert(big_int32_t(value))" instead of "cntr.insert(value)" gets old fast when you are writing application code and the use case arises more or less continuously. Additionally, the use of an endian type is an implementation detail that should not leak into the application code that needs to create values of the type. Furthermore, the ambiguities that caused the constructors to be made explicit no longer occur; they were eliminated when BOOST_MINIMAL_INTEGER_COVER_OPERATORS was introduced to removed a dependency on boost/operators.hpp. If an ambiguity does arise, it is easy to clear via a static_cast or a function-style cast. 2013-09-06 10:36:54 -04:00
Beman
016d3b2e7c Rename the endian typedefs. Rationale: Subjective - during three months working on the B-tree library, the *un_t names were a constant source of irritation. Objective - the new scheme, which reverts the *un_t names to having no alignment decoration, provides consistent *_align* decoration for both FP and integer types. Also, the library now provides conversion functions which may reduce use of aligned endian types. 2013-09-01 08:40:32 -04:00
