Subject: AArch64/opcodes: Correct another `index' global shadowing error
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=329d01f70ea6367a9593c9b31e268c06dd729ec9;p=binutils-gdb.git

AArch64/opcodes: Correct another `index' global shadowing error

Fix a commit c2c4ff8d52a2 ("[AArch64] Add ARMv8.3 FCMLA and FCADD
instructions") build regression:

cc1: warnings being treated as errors
.../opcodes/aarch64-dis.c: In function 'aarch64_ext_sve_addr_rr_lsl':
.../opcodes/aarch64-dis.c:1324: error: declaration of 'index' shadows a global declaration
/usr/include/string.h:303: error: shadowed declaration is here
make[4]: *** [aarch64-asm.lo] Error 1

in a way following commit 91d6fa6a035c ("Add -Wshadow to the gcc command
line options used when compiling the binutils.").

	* aarch64-asm.c (aarch64_ins_reglane): Rename `index' local
	variable to `reglane_index'.
