2.1.10 --bss_threshold=num
This option controls the placement of small global ZI data items in sections. A small
global ZI data item is an uninitialized data item that is eight bytes or less in size.
Syntax
--bss_threshold=num
Where:
num
is either:
0 place small global ZI data items in ZI data sections
8 place small global ZI data items in RW data sections.
Default
If you do not specify a --bss_threshold option, the compiler assumes
--bss_threshold=8.
