Subject: cmse_scan segfault
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8c246a60c08d82066b16973bcd622e671300eb02;p=binutils-gdb.git

cmse_scan segfault

elf_sym_hashes for as-needed libs will be zeroed if the library is
found to be not needed.  More than that, the local symbols for such a
library should not be considered by cmse_scan.

	* elf32-arm.c (elf32_arm_size_stubs): Ignore as-needed libs that
	were not needed.
