[PATCH v2 00/11] gdb/testsuite: Cleanup gdb.base for clang testing

[Bruno Larsen]

When testing GDB with clang, gdb.base had over 50 more failures than when
testing with gcc.  Examining the failed tests led to a few clang bugs, a
few GDB bugs, and many testsuite assumptions that could be changed.

After this patch series, nothing should be changed for testing with gcc,
and testing with clang should only show non-trivial failures for
maint.exp and macscp.exp, along with the same GCC failures.

Changes in v2:
    * Introduced gdb_step_until_regexp, based on Pedro's and Andrew's suggestions
    * reworked fixes for: skip.exp, skip-solib.exp and msym-bp-shl.exp
    * Used Pedro's suggestion for call-ar-st
    * reordered patches slightly

Bruno Larsen (11):
  gdb/testsuite: introduce gdb_step_until_regexp
  Change gdb.base/skip-solib.exp deal with lack of epilogue information
  change gdb.base/skip.exp to use finish instead of step
  change gdb.base/symbol-alias to xfail with clang
  change gdb.base/nodebug.c to not fail with clang
  update gdb.base/info-program.exp to not fail with clang
  fix gdb.base/access-mem-running.exp for clang testing
  Fix gdb.base/call-ar-st to work with Clang
  add xfails to gdb.base/complex-parts.exp when testing with clang
  gdb/testsuite: fix gdb.base/msym-bp-shl when running with Clang
  explicitly test for stderr in gdb.base/dprintf.exp
