Changing section sizes could conceivably result in buffer overflows if section contents were held in memory. Also, keeping the original section sizes allows this PR to be fixed nicely. bfd/ PR 25569 * aoutx.h (adjust_o_magic, adjust_z_magic, adjust_n_magic): Use "text", "data" and "bss" section pointer vars. Don't update section size, just exec header sizes. (adjust_sizes_and_vmas): Don't update text section size. Set initial exec header a_text. Print exec headers sizes. * pdp11.c (adjust_o_magic, adjust_z_magic, adjust_n_magic), (adjust_sizes_and_vmas): Similarly. Formatting. (final_link): Correct final file extension. gas/ PR 25569 * config/obj-aout.c (obj_aout_frob_file_before_fix): Don't loop on section size adjustment, instead perform another write if exec header size is larger than section size. -- You are receiving this mail because: You are on the CC list for the bug.
