r345066:
stand: Improve some debugging experience
Some of these files using <FOO>_DEBUG defined a DEBUG() macro to serve as a
debug-printf. -DDEBUG is useful to enable some debugging output across
multiple ELF/common parts, so switch the DEBUG-as-printf macros over to
something more like DPRINTF that is more commonly used for this kind of
thing and less likely to conflict.
userboot/elf64_freebsd debugging also assumed %llx for uint64; use PRIx64
instead.
r347219:
loader: use safer DPRINTF body for non-debug case
r347220:
loader: bcache code does not need to check argument for free()
r347223:
command_bcache() does not use argv
Therefore mark argv __unused.
r347388:
loader: implement proper 8 char tab stops
The current console code is printing out 8 spaces for tab, calculate
the amount of spaces based on tab stops.
r347389:
loader: ptable_print() needs two tabs sometimes
Since the partition/slice names do vary in length, check the length
of the fixed part of the line against 3 * 8, if the lenth is less than
3 tab stops, print out extra tab.
use snprintf() instead of sprintf.
r347391:
loader: no-TERM_EMU is broken now
If TERM_EMU is not defined, we do not have curx variable. Use conout mode
for efi and expose get_pos() for i386.
r347393:
loader: use DPRINTF in biosdisk.c and define safe DPRINTF
r345066 did miss biosdisk.c.
Also define DPRINTF as ((void)0) for case we do not want debug printouts.
r347553:
loader: fix memory handling errors in module.c
file_loadraw():
check for file_alloc() and strdup() results.
we leak 'name'.
mod_load() does leak 'filename'.
mod_loadkld() does not need to check fp, file_discard() does check.
r348040:
stand: TARGET_ARCH is spelled MACHINE_ARCH in Makefiles
