-Subject: [PATCH] [ARM, sim] Fix build error and warnings
-From: Luis Machado <luis.machado@linaro.org>
-
-Newer GCC's have switched to -fno-common by default, and this breaks the build
-for the ARM sim, like this:
-
-binutils-gdb.git~gdb-8.3-release/sim/arm/maverick.c:65: multiple definition of `DSPsc'; libsim.a(wrapper.o):binutils-gdb.git~gdb-8.3-release/sim/arm/wrapper.c:134: first defined here
-binutils-gdb.git~gdb-8.3-release/sim/arm/maverick.c:64: multiple definition of `DSPacc'; libsim.a(wrapper.o):binutils-gdb.git~gdb-8.3-release/sim/arm/wrapper.c:133: first defined here
-binutils-gdb.git~gdb-8.3-release/sim/arm/maverick.c:63: multiple definition of `DSPregs'; libsim.a(wrapper.o):binutils-gdb.git~gdb-8.3-release/sim/arm/wrapper.c:132: first defined here
-
-I also noticed a few warnings due to mismatching types, as follows:
-
-../../../../repos/binutils-gdb/sim/arm/wrapper.c: In function ‘sim_create_inferior’:
-../../../../repos/binutils-gdb/sim/arm/wrapper.c:335:16: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
- for (arg = argv; *arg != NULL; arg++)
- ^
-../../../../repos/binutils-gdb/sim/arm/wrapper.c:342:8: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
- arg = argv;
- ^
-../../../../repos/binutils-gdb/sim/arm/wrapper.c:345:13: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
- for (arg = argv; *arg != NULL; arg++)
- ^
-The following patch fixes both of the above.
