Bug ID: 18931
Summary: src/gdb/testsuite/gdb.arch/aarch64-fp.c has broken
code in it
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: testsuite
Assignee: unassigned at sourceware dot org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---

The code does:
addr = &buf0[0];
__asm __volatile ("ldr %x0, [%1]" : "=r" (val) : "r" (&addr));
__asm __volatile ("ldr q0, [x0]");


But x0 does not have to be the same as addr.

Fix asm in testsuite/gdb.arch/aarch64-fp.c

Cannot assume result of first and third ldr will go into x0.
Rewrite asm to be clearer.
