Subject: gdb-7.2.50-sparc-add-workaround-to-broken-debug-files.patch
|
|
|
|
;; Toolchain on sparc is slightly broken and debuginfo files are generated
|
|
;; with non 64bit aligned tables/offsets.
|
|
;; See for example readelf -S ../Xvnc.debug.
|
|
;;
|
|
;; As a consenquence calculation of sectp->filepos as used in
|
|
;; dwarf2_read_section (gdb/dwarf2read.c:1525) will return a non aligned buffer
|
|
;; that cannot be used directly as done with MMAP.
|
|
;; Usage will result in a BusError.
|
|
;;
|
|
;; While we figure out what's wrong in the toolchain and do a full archive
|
|
;; rebuild to fix it, we need to be able to use gdb :)
