在arch/blackfin/mach-common/cache.s中，有一系列的语法差异：

[Error ea5004] "../../arch/blackfin/mach-common/cache.S":126 Syntax Error in :

cli R3; nop; nop; CSYNC; sti R3;;

syntax error is at or near text ';'.

Attempting error recovery by ignoring text until the ';'

这个错误对应的语句是：

       CSYNC(R3);

多了个分号。改为：

       CSYNC(R3)

[Error ea5007] "../../arch/blackfin/mach-common/cache.S":128 The label "1:" is illegal because it begins with a digit. If this is GNU assembly source, rewrite to a local temporary name of your choosing. If the GNU assembly code was generated from a macro, the VisualDSP++ preprocessing label auto-generation feature ("?") can be used to generate a unique local label.

 

[Error ea5003] "../../arch/blackfin/mach-common/cache.S":131 Semantic Error in instruction :

IF CC JUMP 1b (bp);

Operands don't fit instruction template 'IF CC JUMP expr'.

Check for an out of range immediate value or an illegal register.

 

[Error ea5004] "../../arch/blackfin/mach-common/cache.S":131 Syntax Error in :

IF CC JUMP 1b (bp);

syntax error is at or near text 'b'.

Attempting error recovery by ignoring text until the ';'

对应的语句为：

1:

       IFLUSH [P0++];

       CC = P0 < P1 (iu);

       IF CC JUMP 1b (bp);

改为：

_blackfin_icache_flush_range_1:

       IFLUSH [P0++];

       CC = P0 < P1 (iu);

       IF CC JUMP _blackfin_icache_flush_range_1 (bp);

[Error ea5004] "../../arch/blackfin/mach-common/cache.S":133 Syntax Error in :

cli R3; nop; nop; SSYNC; sti R3;;

syntax error is at or near text ';'.

Attempting error recovery by ignoring text until the ';'

对应的语句为：

       SSYNC(R3);

改为：

       SSYNC(R3)
