我想为我的精灵定义一个bss部分。但是当我google for it it时，仅使用.section指令支持ELF目标。
a section is allocatable
e section is excluded from executable and shared library.
w section is writable
x section is executable
M section is mergeable
S section contains zero terminated strings
G section is a member of a section group
T section is used for thread-local-storage
? section is a member of the previously-current section's group, if any
任何人都可以帮我指定bss部分或任何替代选项。
