From 6bc14195fbb32e37476369b36d4e6a670c1ec1e9 Mon Sep 17 00:00:00 2001 From: Jeff Law Date: Sun, 31 Oct 1993 01:54:01 +0000 Subject: Rework space/subspace handling in PA code to fully support SOM spaces/subspaces. * tc-hppa.c (USE_ALIASES): New object-format dependent define to control the use of space/subspace name aliases. (update_subspace): Accept space chain entry for containing space as a new parameter. All callers changed. (pa_get_label): Use current_space rather than pa_segment_to_space. (pa_define_label): Likewise. (pa_undefine_label): Likewise. (md_begin): Change into the (possibly modified) text_section. (pa_parse_space_stmt): Create a new segment/space if create_flag is true, and the space name is not one of the two predefined spaces. (pa_subspace): Use current_space rather than a lookup via pa_segment_to_space. Reset BFD section flags as required by the .subspace directive. Likewise for the section alignment. Pass the current space to update_subspace and create_new_subspace. (pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES is true. When not using aliases, create a BFD section for each subspace encountered. When not using aliases replace the default text, data, and bss segments with new ones. (create_new_subspace): When not using aliases each subspace has a section/segment and subsegments are not needed, so set the subsegment to zero. --- gas/ChangeLog | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'gas') diff --git a/gas/ChangeLog b/gas/ChangeLog index 96c6b40..675b049 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,5 +1,29 @@ Sat Oct 30 14:26:20 1993 Jeffrey A.
