Subject: Fix compilation error with clang in gdb/testsuite/gdb.base/jit-main.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e0c45f305525bbc3fd95024e4517a52d1c371868;p=binutils-gdb.git

Fix compilation error with clang in gdb/testsuite/gdb.base/jit-main.c

Clang fails to compile the above file, with the following error:
  warning: while loop has empty body [-Wempty-body]

This prevents the following testcases from executing:
  gdb.base/jit.exp
  gdb.base/jit-so.exp
