/**
|

|
* The public interface of this header consists of a set of macros and
|

|
* functions for Intel CPU features.
|
||||||
|
*
|
||||||
|
* CODE USING ASSEMBLY
|
||||||
|
* ===================
|
||||||
|
*
|
||||||
|
* For each feature handled here, this header defines a single function
|
||||||
|
* that can be used to test whether to use code written in *assembly*:
|
||||||
|
* mozilla::supports_mmx
|
||||||
|
* mozilla::supports_sse
|
||||||
|
* mozilla::supports_sse2
|
||||||
|
* mozilla::supports_sse3
|
||||||
|
* mozilla::supports_ssse3
|
||||||
|
* mozilla::supports_sse4a
|
||||||
|
* mozilla::supports_sse4_1
|
||||||
|
* mozilla::supports_sse4_2
|
||||||
|
* Note that the dynamic detection depends on cpuid intrinsics only
|
||||||
|
* available in gcc 4.3 or later and MSVC 8.0 (Visual C++ 2005) or
|
||||||
|
* later, so the dynamic detection returns false in older compilers.
|
||||||
|
* (This could be fixed by replacing the code with inline assembly.)
|
||||||
|
*
|
||||||
|
* CODE USING INTRINSICS
|
||||||
|
* =====================
|
||||||
|
*
|
||||||
|
* The remainder of the functions and macros that are the API from this
|
||||||
|
* header relate to code written using CPU intrinsics.
|
||||||
|
*
|
||||||
|
* In each macro-function pair, the function may not be available if the
|
||||||
|
* macro is undefined. They should be used in the following pattern:
|
||||||
|
*
|
||||||
|
* if (mozilla::use_abc()) {
|
||||||
|
* #ifdef MOZILLA_COMPILE_WITH_ABC
|
||||||
|
* // abc-specific code here
|
||||||
|
* #endif
|
||||||
|
* } else {
|
||||||
|
* // generic code here
|
||||||
|
* }
|
||||||
|
*
|
||||||
|
* In addition, on some platforms, the headers that contain the
|
||||||
|
* intrinsics for many of these features won't compile unless we define
|
||||||
|
* a particular macro first (to pretend that we gave gcc an appropriate
|
||||||
|
* -march option). Therefore, code using this header should NOT include
|
||||||
|
* the headers for intrinsics directly, but should instead request the
|
||||||
|
* header by defining the header macro given below *before* including
|
||||||
|
* this file (which, in practice, means before including *any* header
|
||||||
|
* files).
|
||||||
|
*
|
||||||
|
* The dynamic detection depends on cpuid intrinsics only available in
|
||||||
|
* gcc 4.3 or later and MSVC 8.0 (Visual C++ 2005) or later, so the
|
||||||
|
* dynamic detection returns false in older compilers. However, it
|
||||||
|
* could be extended to avoid this restriction; see the code in
|
||||||
|
* mozilla/jpeg/jdapimin.c for some hints.
