Hi, List,
After upgrading from z/OS 1.9 to z/OS 1.11, all our metal c programs just
won't pass the compilation process.
Take a simple test program for example:
#include <metal.h>
#include <string.h>
void main()
{
_asm(" here we are " );
}
It does pass the compilation, but the generated asm code is different from
before:
56 * _asm(" here we are " );
57 LR 14,11
58 OILH 14,X'8000'
59 L 15,=V(@ASM)
60 LA 1,76(,13)
61 ST 14,76(,13)
62 MVC 8(4,13),#NAB_1
63 BASR 14,15
I remember clearly that in z/OS 1.9 "here we are" will be generated as-is
in the asm souce code.
Ok, let's add the ":":
#include <metal.h>
#include <string.h>
void main()
{
_asm(" here we are " : : : );
}
Then the compilation failed:
5 1 | _asm(" here we are " : : : );
===========> .......................a.................................
*=ERROR===========> a - CCN3276 Syntax error: possible missing ')'?
Actually all our programs which use ':' in _asm code encounter the same
'missing ')' ' error.
And those programs work well in the past.
My search parm is :
NOSEARCH,SOURCE,SEARCH(/usr/include/metal/)
It seems to me that metal c compiler suddenly goes crazy...
Any hint?
Thanks.
Best Regards,
Johnny Luo
