bfd_size_type was invented a long time ago in the K&R days. Many places in binutils ought to be using size_t instead (and there are lots of places that use long or unsigned long that really ought to use size_t too). Note that you can't change everything over to size_t: A 32-bit host needs a larger type than size_t to support reading and processing of 64-bit ELF object files. This patch just tidies some of the more obvious uses of bfd_size_type that could be size_t. There no doubt are more lurking in the source. Incidentally, practically all functions used for output of object files can use size_t and don't need to worry about overflow of size expressions. If you have something like symcount * sizeof (void *) when symcount is counting symbols already in memory then you know that this expression can't overflow since the size of a symbol in memory is larger by far than that of a pointer. * aix386-core.c (aix386_core_file_p): Use size_t for "amt". * aout-target.h (object_p): Likewise. * aout-tic30.c (tic30_aout_object_p): Likewise. * aoutx.h

data.
|
||
|

This is very simple. The only complication is that the real data
|

will start at some address X, and in some cases we will not want to
|
||
include X zeroes just to get to that point. Since the start
|
||
address is not meaningful for this object file format, we use it
|
||
instead to indicate the number of zeroes to skip at the start of
|
||
the file. objcopy cooperates by specially setting the start
|
||
address to zero by default. */
