From: Kevin Buettner Date: Sat, 11 Jul 2015 00:41:55 +0000 (-0700) Subject: dwarf2read: Allow SEC_ALLOC sections to be located at address 0. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b4e1fd615ae6582170a6bb62d6519d586bd5347e;p=binutils-gdb.git dwarf2read: Allow SEC_ALLOC sections to be located at address 0. GDB already allows statically initialized variables, located in SEC_LOAD sections, to be placed at address 0. This change allows uninitialized variables (which are in SEC_ALLOC sections) to be placed address 0 as well. gdb/ChangeLog: * dwarf2read.c (dwarf2_locate_sections): Allow has_section_at_zero to be set for SEC_ALLOC sections too. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 3bd64ab16f8..7f31ff58c9a 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2015-07-18 Kevin Buettner + + * dwarf2read.c (dwarf2_locate_sections): Allow has_section_at_zero + to be set for SEC_ALLOC sections too. + 2015-07-17 Yao Qi * Makefile.in (HFILES_NO_SRCDIR): Add diff --git a/gdb/dwarf2read.c b/gdb/dwarf2read.c index 91c6a8feeee..f44095683fb 100644 --- a/gdb/dwarf2read.c +++ b/gdb/dwarf2read.c @@ -2241,7 +2241,7 @@ dwarf2_locate_sections (bfd *abfd, asection *sectp, void *vnames) dwarf2_per_objfile->gdb_index.size = bfd_get_section_size (sectp); } - if ((bfd_get_section_flags (abfd, sectp) & SEC_LOAD) + if ((bfd_get_section_flags (abfd, sectp) & (SEC_LOAD | SEC_ALLOC)) && bfd_section_vma (abfd, sectp) == 0) dwarf2_per_objfile->has_section_at_zero = 1; }
