What ild Cannot Do

When ild is invoked to create shared objects, ild invokes ld to do the link.

Performance of ild may suffer greatly if you change a high percentage of object files. ild automatically does an full relink when it detects that a high percentage of files have been changed.

Do not use ild to produce the final production code for shipment. ild makes the file larger because parts of the program have been spread out due to padding. Because of the padding and additional time required to link, it is recommended that you do not use the -xildon option for production code. (Use -xildoff on the link line if -g is present.)

ild may not link small programs much faster, and the increase in size of the executable is greater than that for larger programs.

Third-party tools that work on executables may have unexpected results on ild-produced binaries.

Any program that modifies an executable, for example strip or mcs, might affect the ability of ild to perform an incremental link. When this happens, ild issues a message and performs a full relink. See "Reasons for Full Relinks" and "Example 2: running strip".
