Summary: gdb.Block should expose whether the block is special
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: python
AssignedTo: unassigned@sourceware.org
ReportedBy: tromey@redhat.com
Right now there is no clean way to discover that a block
is a global or static block from python.
There should be a method or two for this.

Notes for Phil Muldoon which are more general and may not be specific for this
Bug:
http://sourceware.org/ml/gdb-patches/2011-04/msg00143.html
# There is still gdbpy_block_for_pc (unaffected by this patch at all) which
# works as described but it may be confusing as it does not behave well with
# inlined functions when used as is.
I do not see block_for_pc to be used in the .py scripts shipped in GDB but any
such use should be reviewed wrt inlined functions correctness.
One should always derive block from its frame by get_frame_block. Relying on
any PC there may produce incorrect results. Which should be already done fine
by frapy_block.
frapy_block should never need to return GLOBAL_BLOC or STATIC_BLOCK so there
should not be a problem the current code does not allow it.
Maybe everything is correct and nothing needs to be changed now, thanks.

The return values are correct; but the problem in this bug is that
you can look upwards using Block.superblock -- but then you have no good
way to know when to stop searching upward.
