On 32-bit and 64-bit x86 targets, you can use an ABI attribute
to indicate which calling convention should be used for a function. The
@code{ms_abi} attribute tells the compiler to use the Microsoft ABI,
-while the @code{sysv_abi} attribute tells the compiler to use the ABI
-used on GNU/Linux and other systems. The default is to use the Microsoft ABI
-when targeting Windows. On all other systems, the default is the x86/AMD ABI.
+while the @code{sysv_abi} attribute tells the compiler to use the System V
+ELF ABI, which is used on GNU/Linux and other systems. The default is to use
+the Microsoft ABI when targeting Windows. On all other systems, the default
+is the System V ELF ABI.
Note, the @code{ms_abi} attribute for Microsoft Windows 64-bit targets currently
requires the @option{-maccumulate-outgoing-args} option.
