* Add support for delay importing to dlltool. Use the --output-delaylib <file>
|
||||
switch to create a delay-import library. The resulting app will load the dll
|
||||
as soon as the first function is called. It will link to __delayLoadHelper2()
|
||||
from the static delayimp library, which will import LoadLibraryA and
|
||||
GetProcAddress from kernel32.
|
||||
|
||||
* Add a new command line option, --insn-width=WIDTH, to objdump to specify
|
||||
number of bytes to be displayed on a single line when disassembling
|
||||
instructions.

|
||||
of bytes via the --relocated-dump=<name|number> command line option.
