This was all done with a script, no manual editing involved, but I audited the patch to make sure things were converted as expected. This is split from the previous patch only for review and maintanance convencience. I plan on merging this with the previous patch before pushing. --- gdb/ada-lang.c | 42 ++++--- gdb/ada-typeprint.c | 7 +- gdb/ada-valprint.c | 7 +- gdb/amd64-tdep.c | 18 +-- gdb/break-catch-throw.c | 22 ++-- gdb/breakpoint.c | 80 +++++++------ gdb/btrace.c | 18 ++- gdb/c-varobj.c | 33 ++++-- gdb/cli/cli-interp.c | 6 +- gdb/cli/cli-script.c | 12 +- gdb/compile/compile-c-symbols.c | 27 +++-- gdb/compile/compile-object-run.c | 6 +- gdb/completer.c | 11 +- gdb/corelow.c | 19 ++-- gdb/cp-abi.c | 17 +-- gdb/cp-support.c | 20 +++- gdb/cp-valprint.c | 21 ++-- gdb/dwarf2-frame-tailcall.c | 6 +- gdb/dwarf2-frame.c | 17 +-- gdb/dwarf2loc.c | 13 ++- gdb/dwarf2read.c | 24 ++-- gdb/eval.c | 33 +++--- gdb/event-loop.c | 7 +- gdb/event-top.c | 12 +- gdb/exceptions.c | 13 ++- gdb/f-valprint.c | 11 +- gdb/frame-unwind.c | 6 +- gdb/frame.c | 25 ++-- gdb/gcore.c | 14 ++- gdb/gdbserver/server.c | 20 ++-- gdb/gdbtypes.c | 20 ++-- gdb/gnu-v3-abi.c | 11 +- gdb/guile/guile.c | 8 +- gdb/guile/scm-block.c | 9 +- gdb/guile/scm-breakpoint.c | 75 ++++++++---- gdb/guile/scm-cmd.c | 9 +- gdb/guile/scm-disasm.c | 9 +- gdb/guile/scm-frame.c | 166 ++++++++++++++++++--------- gdb/guile/scm-lazy-string.c | 15 ++- gdb/guile/scm-math.c | 36 ++++-- gdb/guile/scm-param.c | 17 ++- gdb/guile/scm-ports.c | 9 +- gdb/guile/scm-pretty-print.c | 7 +- gdb/guile/scm-symbol.c | 42 +++++-- gdb/guile/scm-symtab.c | 9 +- gdb/guile/scm-type.c | 105 +++++++++++------ gdb/guile/scm-value.c | 240 ++++++++++++++++++++++++++------------- gdb/i386-tdep.c | 18 +-- gdb/inf-loop.c | 14 ++- gdb/infcall.c | 6 +- gdb/infcmd.c | 16 +-- gdb/infrun.c | 20 ++-- gdb/jit.c | 16 ++- gdb/linespec.c | 12 +- gdb/linux-nat.c | 6 +- gdb/linux-tdep.c | 11 +- gdb/linux-thread-db.c | 19 ++-- gdb/main.c | 16 ++- gdb/mi/mi-cmd-stack.c | 7 +- gdb/mi/mi-interp.c | 24 +++- gdb/mi/mi-main.c | 13 ++- gdb/p-valprint.c | 6 +- gdb/parse.c | 12 +- gdb/ppc-linux-tdep.c | 10 +- gdb/printcmd.c | 40 ++++--- gdb/python/py-arch.c | 6 +- gdb/python/py-block.c | 9 +- gdb/python/py-breakpoint.c | 55 +++++---- gdb/python/py-cmd.c | 7 +- gdb/python/py-finishbreakpoint.c | 38 ++++--- gdb/python/py-frame.c | 158 +++++++++++++++++--------- gdb/python/py-framefilter.c | 134 ++++++++++++---------- gdb/python/py-gdb-readline.c | 10 +- gdb/python/py-inferior.c | 35 ++++-- gdb/python/py-infthread.c | 9 +- gdb/python/py-lazy-string.c | 9 +- gdb/python/py-linetable.c | 9 +- gdb/python/py-objfile.c | 18 ++- gdb/python/py-param.c | 7 +- gdb/python/py-prettyprint.c | 16 ++- gdb/python/py-symbol.c | 45 +++++--- gdb/python/py-type.c | 147 ++++++++++++++++-------- gdb/python/py-utils.c | 9 +- gdb/python/py-value.c | 224 ++++++++++++++++++++++++------------ gdb/python/python.c | 64 +++++++---- gdb/record-btrace.c | 67 +++++++---- gdb/remote.c | 35 +++--- gdb/rs6000-aix-tdep.c | 7 +- gdb/rs6000-tdep.c | 6 +- gdb/s390-linux-tdep.c | 6 +- gdb/solib-dsbt.c | 8 +- gdb/solib-frv.c | 8 +- gdb/solib-ia64-hpux.c | 20 ++-- gdb/solib-spu.c | 6 +- gdb/solib-svr4.c | 19 +++- gdb/solib.c | 48 ++++---- gdb/stack.c | 77 +++++++++---- gdb/symtab.c | 6 +- gdb/target.c | 6 +- gdb/top.c | 37 +++--- gdb/tracefile-tfile.c | 6 +- gdb/tui/tui.c | 6 +- gdb/typeprint.c | 10 +- gdb/valops.c | 13 ++- gdb/valprint.c | 10 +- gdb/value.c | 11 +- gdb/varobj.c | 40 ++++--- gdb/xml-support.c | 12 +- 108 files changed, 1968 insertions(+), 1125 deletions(-) diff --git a/gdb/ada-lang.c b/gdb/ada-lang.c index 04cff1e..b9887ec 100644 --- a/gdb/ada-lang.c +++ b/gdb/ada-lang.c @@ -6480,7 +6480,6 @@ type_from_tag (struct value *tag) struct value * ada_tag_value_at_base_address (struct value *obj) { - volatile struct gdb_exception e; struct value *val; LONGEST offset_to_top = 0; struct type *ptr_type, *obj_type; @@ -6515,13 +6514,16 @@ ada_tag_value_at_base_address (struct value *obj) see ada_tag_name for more details.
