Each of the macros in this section is used to do the whole job of outputting a single uninitialized variable.
ASM_OUTPUT_COMMON (stream, name, size, rounded)
Use the expression assemble_name (stream, name)
to
output the name itself; before and after that, output the additional
assembler syntax for defining the name, and a newline.
This macro controls how the assembler definitions of uninitialized global variables are output.
ASM_OUTPUT_ALIGNED_COMMON (stream, name, size, alignment)
ASM_OUTPUT_COMMON
except takes the required alignment as a
separate, explicit argument. If you define this macro, it is used in
place of ASM_OUTPUT_COMMON
, and gives you more flexibility in
handling the required alignment of the variable. The alignment is specified
as the number of bits.
ASM_OUTPUT_SHARED_COMMON (stream, name, size, rounded)
ASM_OUTPUT_COMMON
, except that it
is used when name is shared. If not defined, ASM_OUTPUT_COMMON
will be used.
ASM_OUTPUT_LOCAL (stream, name, size, rounded)
Use the expression assemble_name (stream, name)
to
output the name itself; before and after that, output the additional
assembler syntax for defining the name, and a newline.
This macro controls how the assembler definitions of uninitialized static variables are output.
ASM_OUTPUT_ALIGNED_LOCAL (stream, name, size, alignment)
ASM_OUTPUT_LOCAL
except takes the required alignment as a
separate, explicit argument. If you define this macro, it is used in
place of ASM_OUTPUT_LOCAL
, and gives you more flexibility in
handling the required alignment of the variable. The alignment is specified
as the number of bits.
ASM_OUTPUT_SHARED_LOCAL (stream, name, size, rounded)
ASM_OUTPUT_LOCAL
, except that it
is used when name is shared. If not defined, ASM_OUTPUT_LOCAL
will be used.
