Hello, ping for https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02625.html a patch proposal to fix exception propagation on spe powerpc targets. The idea is to improve expand_builtin_init_dwarf_reg_sizes to account for register spans as other functions in dwarf2cfi.c do, by extracting the processing for one dwarf register in a separate function. The original patch merged that plus an adjustment to account for DWARF_REG_TO_UNWIND_COLUMN. The two things are splitted apart here to facilitate review. Thanks in advance for your feedback, With Kind Regards, Olivier -- Patch1 (dwregspan.diff) 2014-10-15 Olivier Hainque <hainque@adacore.com> * dwarf2cfi.c (init_one_dwarf_reg_size): New helper, processing one particular reg for expand_builtin_init_dwarf_reg_sizes. (expand_builtin_init_dwarf_reg_sizes): Rework to use helper and account for dwarf register spans. Patch2 (uwcolumn.diff) 2014-10-15 Olivier Hainque <hainque@adacore.com> libgcc/ * unwind-dw2.c (DWARF_REG_TO_UNWIND_COLUMN): Move default def to ... gcc/ * defaults.h: ... here. * dwarf2cfi.c (init_one_dwarf_reg_size): Honor DWARF_REG_TO_UNWIND_COLUMN.
