By calling `uplevel $body` in the program proc (a pattern we use at many places), we can get rid of curly braces around each line number program directive. That seems like a nice small improvement to me. Change-Id: Ib327edcbffbd4c23a08614adee56c12ea25ebc0b

# Lookup a type in a partial unit with DW_AT_stmt_list.
|
|
#
|
|
# The test-case is setup such that the partial symtab expansion route is
|
|
# .h partial symtab -> shared partial symtab -> toplevel symtab.
|
|
#
|
|
# That is, the partial symtabs (as displayed by maint print objfiles) are:
|
|
#
|
|
# ../sysdeps/x86_64/crtn.S at 0x3d944e0^M
|
|
# elf-init.c at 0x3d94440^M
|
|
# dw2-symtab-includes.h at 0x3d7c7a0^M
|
|
# <unknown> at 0x31ef870^M
|
|
# bla.c at 0x33985f0^M
|
|
# ../sysdeps/x86_64/crti.S at 0x33e9a00^M
|
|
# init.c at 0x33fa600^M
|
|
# ../sysdeps/x86_64/start.S at 0x33f3fd0^M
|
|
#
|
|
# and the expansion of dw2-symtab-includes.h triggers the expansion of its
|
|
# includer <unknown>, which triggers expansion of user bla.c.
|
|
#
|
|
# The problem in PR28539 was that after expansion of dw2-symtab-includes.h
|
|
# the expansion_notify function in psymbol_functions::expand_symtabs_matching
|
|
# should be called with the bla.c symtab, but instead it got called with
|
|
# nullptr, which caused a segfault.
