Hi,

In AIX, unless and until the debugee uses the vector registers, one cannot fetch or write on them. Hence any ptrace () call will not be able to fetch or set the vector registers. Currently the test case sets a breakpoint in the main and makes an attempt to set the vector registers which will not work in AIX.

This patch ensures the completion of the execution of the line that uses vector registers first time only in AIX target.

Then the testcase will be able to set and fetch the vector registers.

For the remaining targets test case will stay as it is.

Please find attached the patch. [See:- 0001-Modify-altivec-regs.exp-testcase-for-AIX.patch]

Kindly let me know what you think.

Thanks and regards,
Aditya.
