| |
The macro insn_fetch marks the 'type' argument as having a specified alignment. Type attributes can only be applied to structs, unions, or enums, but insn_fetch is only ever invoked with integral types, so Clang produces 19 -Wignored-attributes warnings for this source file.
Signed-off-by: Nick Desaulniers <nick.desaulniers@gmail.com> --- Changes in v2: * prefer memcpy * fix up trailing tabs
