有' />个' />:

[Error ea5004] "..\..\linux-2.6.x\' />\asm/mach-common/context.S":35 Syntax Error in :

.macro save_context_with_' />errupts

syntax error is at or near text 'save_context_with_' />errupts'.

Attempting error recovery by ignoring text until the ';'

其指向' />' />代码为:

/*

* 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_' />errupts

……………….

/* Switch to other method of keeping ' />errupts disabled. */

#' />def CONFIG_DEBUG_HWERR

r0 = 0x3f;

sti r0;

#' />

cli r0;

#end' />

………………………

.endm

这里有两个问题' />首先是vdsp' />汇编器不支持.macro' />只能用#' />来替代' />第 2个是在里面出现了#' />def这样' />条件判断' />只能将移到宏定义' />外面' />修改后' />代码为:

#' />def CONFIG_DEBUG_HWERR



#' /> save_context_with_' />errupts \

……………….. \

/* Switch to other method of keeping ' />errupts disabled. */ \

r0 = 0x3f; \

sti r0; \

………………. \

//.endm



#' />



#' /> save_context_with_' />errupts \

……………………….. \

/* Switch to other method of keeping ' />errupts disabled. */ \

cli r0; \

……………………….. \

//.endm



#end' /> // CONFIG_DEBUG_HWERR

其它宏' />修改和此类似' />
