In man ld you can see:
<cut>
--enable-new-dtags
--disable-new-dtags
This linker can create the new dynamic tags in ELF. But the older ELF
systems may not understand them. If you specify --enable-new-dtags,
the dynamic tags will be created as needed. If you specify --dis‐
able-new-dtags, no new dynamic tags will be created. By default, the
new dynamic tags are not created. Note that those options are only
available for ELF systems.
Set the default size of the linker
In man ld you can see:
<cut>
--enable-new-dtags
--disable-new-dtags
This linker can create the new dynamic tags in ELF. But the older ELF
systems may not understand them. If you specify --enable-new-dtags,
the dynamic tags will be created as needed. If you specify --dis‐
able-new-dtags, no new dynamic tags will be created. By default, the
new dynamic tags are not created. Note that those options are only
available for ELF systems.
Set the default size of the linkers hash tables to a prime number
close to number. Increasing this value can reduce the length of time
it takes the linker to perform its tasks, at the expense of increasing
the linkers memory requirements. Similarly reducing this value can
reduce the memory requirements at the expense of speed.
<cut>
And I think it should be:
<cut>
--enable-new-dtags
--disable-new-dtags
This linker can create the new dynamic tags in ELF. But the older ELF
systems may not understand them. If you specify --enable-new-dtags,
the dynamic tags will be created as needed. If you specify --dis‐
able-new-dtags, no new dynamic tags will be created. By default, the
new dynamic tags are not created. Note that those options are only
available for ELF systems.
--hash-size=number
Set the default size of the linkers hash tables to a prime number
close to number. Increasing this value can reduce the length of time
it takes the linker to perform its tasks, at the expense of increasing
the linkers memory requirements. Similarly reducing this value can
reduce the memory requirements at the expense of speed.
<cut>
The second paragraph is describing the --hash-size option, but does not say so.
