新版本——

作者：zyl910。
之前的ccpuid V1.01版只支持Windows和Linux平台。現在的V1.02版增加對Mac OS X平台的支持，還做了這些改進——支持純C、增加CPUF常數、x86平台判斷。
一、更新說明
1.1 支持Mac OS X平台
之前我發現了Mac OS X中的“/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/4.0/include”目錄中有intrin頭文件（http://www.cnblogs.com/zyl910/archive/2012/09/27/intrin_mac.html）。於是以為ccpuid不經過修改便能在Mac OS C中編譯。但是實際測試時發現，gcc報告找不到“cpuid.h”。
但是很奇怪，“#include <xmmintrin.h>”卻能正常包含。
雖然修改gcc的目錄配置也許能解決問題，但我沒有這么做，因為這樣會增加配置成本。
而且，打開Mac OS X中的cpuid.h一看，發現它沒有定義__cpuid/__cpuid_count等宏。也就是說，就算正確包含了cpuid.h，也因缺少相關宏而報錯。
換一下思路，直接使用內嵌匯編行不行呢？
VC中的內嵌匯編不支持64位，於是只有使用intrin函數。而gcc的內嵌匯編不受該限制，64位下也可使用內嵌匯編，例如Fedora的cpuid.h中就是用內嵌匯編實現__cpuid等宏的。
Mac下的gcc也是一種gcc，內嵌匯編的語法應該是一樣的。
於是我試着將Fedora的cpuid.h中關於__cpuid等宏的的代碼，用Mac下的gcc編譯。果然編譯成功，運行正常。
__cpuid的相關代碼修改成——
#include <xmmintrin.h> // MMX, SSE //#include <cpuid.h> // mac 中的 llvm-gcc有時找不到cpuid.h，而且它沒有 __cpuid/__cpuid_count，干脆我們自己定義. #ifndef __cpuid_count // 下面代碼出自 GCC 4.7.0(Fedora 17) 的 cpuid.h #if defined(__i386__) && defined(__PIC__) /* %ebx may be the PIC register. */ #if __GNUC__ >= 3 #define __cpuid(level, a, b, c, d) \ __asm__ ("xchg{l}\t{%%}ebx, %1\n\t" \ "cpuid\n\t" \ "xchg{l}\t{%%}ebx, %1\n\t" \ : "=a" (a), "=r" (b), "=c" (c), "=d" (d) \ : "0" (level)) #define __cpuid_count(level, count, a, b, c, d) \ __asm__ ("xchg{l}\t{%%}ebx, %1\n\t" \ "cpuid\n\t" \ "xchg{l}\t{%%}ebx, %1\n\t" \ : "=a" (a), "=r" (b), "=c" (c), "=d" (d) \ : "0" (level), "2" (count)) #else /* Host GCCs older than 3.0 weren't supporting Intel asm syntax nor alternatives in i386 code. */ #define __cpuid(level, a, b, c, d) \ __asm__ ("xchgl\t%%ebx, %1\n\t" \ "cpuid\n\t" \ "xchgl\t%%ebx, %1\n\t" \ : "=a" (a), "=r" (b), "=c" (c), "=d" (d) \ : "0" (level)) #define __cpuid_count(level, count, a, b, c, d) \ __asm__ ("xchgl\t%%ebx, %1\n\t" \ "cpuid\n\t" \ "xchgl\t%%ebx, %1\n\t" \ : "=a" (a), "=r" (b), "=c" (c), "=d" (d) \ : "0" (level), "2" (count)) #endif #else #define __cpuid(level, a, b, c, d) \ __asm__ ("cpuid\n\t" \ : "=a" (a), "=b" (b), "=c" (c), "=d" (d) \ : "0" (level)) #define __cpuid_count(level, count, a, b, c, d) \ __asm__ ("cpuid\n\t" \ : "=a" (a), "=b" (b), "=c" (c), "=d" (d) \ : "0" (level), "2" (count)) #endif #endif // #ifndef __cpuid_count
1.2 支持純C
ccpuid最初為了使用方便，於是將其封裝成類，使得只有C++程序才能使用該模塊，而純C程序不能使用。
現在決定將其拆分為純C版和C++版，使純C程序也能使用。
具體做法是——
1. 將原 ccpuid.h 拆分為 ccpuid.h 與 ccpuid.hpp。純C的依然保留在ccpuid.h，而C++部分移至ccpuid.hpp。
2. ccpuid.cpp中的全局函數移至ccpuid.h，並作為內聯函數。
3. 因純C不支持結構化異常處理, 忽略simd_mmx、simd_sse_level的 操作系統判斷。
使用方法——
1. 對於純C程序：只需引入ccpuid.h這個頭文件就行了。
2. 對於C++程序：引入ccpuid.hpp，並在項目中加上ccpuid.cpp這個源文件一起編譯。
注意為了避免全局變量問題，CPUFDesc、SseNames等數組仍是作為CCPUID類的靜態成員，所以它們只能在C++版中使用。
1.3 增加CPUF常數
根據最新的Intel文檔——
《Intel® 64 and IA-32 Architectures Software Developer’s Manual Combined Volumes:1, 2A, 2B, 2C, 3A, 3B, and 3C》044US. August 2012. http://www.intel.com/content/www/us/en/processors/architectures-software-developer-manuals.html
《Intel® Architecture Instruction Set Extensions Programming Reference》014. AUGUST 2012. http://software.intel.com/en-us/avx/
《Intel® Processor Identification and the CPUID Instruction》. May 2012. http://developer.intel.com/content/www/us/en/processors/processor-identification-cpuid-instruction-note.html
增加了這些CPUF常數——
CPUID.(EAX=07H, ECX=0H):EBX.TSC_ADJUST(bit 1). // IA32_TSC_ADJUST MSR is supported if 1.
CPUID.(EAX=07H, ECX=0H):EBX.RDSEED(bit 18) // RDSEED instruction.
CPUID.(EAX=07H, ECX=0H):EBX.ADX(bit 19) // ADCX and ADOX instructions.
CPUID.(EAX=07H, ECX=0H):EBX.SMAP(bit 20) // Supervisor Mode Access Prevention.
1.4 x86平台判斷
以前沒有考慮平台檢查，在非x86平台上編譯時會報錯。於是在V1.02版中加入了平台判斷，在非x86平台上返回0而不是無法編譯。
判斷x86平台的具體做法是——
1. 對於GCC：判斷 __i386__ 或 __x86_64__ 宏是否存在。
2. 對於VC：判斷 _M_IX86 或 _M_X64 宏是否存在。
然后根據上面的判斷結果定義CCPUID_X86宏。在simd_mmx等函數中就可以利用CCPUID_X86宏來避免編譯出錯。
這樣做的有利於代碼的移植。例如某個程序使用了ccpuid來判斷CPU是否支持SSE，在x86平台上可以正常檢查，而在非x86平台上能返回0表示不支持，使得后續的SSE代碼不會在非x86平台上運行。
