gcc: S/390 Pragmas

1 
1 6.61.6 S/390 Pragmas
1 --------------------
1 
1 The pragmas defined by the S/390 target correspond to the S/390 target
1 function attributes and some the additional options:
1 
1 'zvector'
1 'no-zvector'
1 
1  Note that options of the pragma, unlike options of the target
1 attribute, do change the value of preprocessor macros like '__VEC__'.
1 They can be specified as below:
1 
1      #pragma GCC target("string[,string]...")
1      #pragma GCC target("string"[,"string"]...)
