uclinux-2008R1.5-RC3(bf561)到VDSP5的移植

有一個錯誤：
    [Error ea5004] "..\..\linux-2.6.x\include\asm/mach-common/context.S":35 Syntax Error in :
    .macro save_context_with_interrupts
    syntax error is at or near text ’save_context_with_interrupts’.
    Attempting error recovery by ignoring text until the ’;’
    其指向的錯誤代碼為：
    /*
    * Code to save processor context.
    * We even save the register which are preserved by a function call
    * - r4, r5, r6, r7, p3, p4, p5
    */
    .macro save_context_with_interrupts
    ……………….
    /* Switch to other method of keeping interrupts disabled. */
    #ifdef CONFIG_DEBUG_HWERR
    r0 = 0x3f;
    sti r0;
    #else
    cli r0;
    #endif
    ………………………
    .endm
    這里有兩個問題，首先是vdsp的匯編器不支持.macro，只能用#define來替代，第二個是在里面出現(xiàn)了#ifdef這樣的條件判斷，只能將之移到宏定義的外面，修改后的代碼為：
    #ifdef CONFIG_DEBUG_HWERR
    #define save_context_with_interrupts \
    ……………….. \
    /* Switch to other method of keeping interrupts disabled. */ \
    r0 = 0x3f; \
    sti r0; \
    ………………. \
    //.endm
    #else
    #define save_context_with_interrupts \
    ……………………….. \
    /* Switch to other method of keeping interrupts disabled. */ \
    cli r0; \
    ……………………….. \
    //.endm
    #endif // CONFIG_DEBUG_HWERR
    其它宏的修改與此類似。
