2011-11-11linux-user/elfload.c: Don't memset(NULL..) if malloc() failedPeter Maydell1-1/+1
If a malloc() in copy_elf_strings() failed we would call memset() before the "did malloc fail?" check. Fix this by moving to the glib alloc/free routines for this memory so we can use g_try_malloc0 rather than having a separate memset(). Spotted by Coverity (see bug 887883).

2011-01-07Remove dead code for ARM semihosting commandline handlingWolfgang Schildbach1-2/+0
There are some bits in the code which were used to store the commandline for the semihosting call. These bits are now write-only and can be removed.

2010-07-29linux-user: Reduce lseek+reads while loading elf files.Richard Henderson1-10/+7
Define BPRM_BUF_SIZE to 1k and read that amount initially. If the data we want from the binary is in this buffer, use it instead of reading from the file again. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2010-04-25linux-user: Remove ELFLOAD32.Richard Henderson1-5/+1
The ABI-specific types used by linux_binprm and image_info are different after forcing TARGET_ABI32 on. Which means that the parameters that load_elf_binary_multi sees are not those that loader_exec passed. This is inherently broken and is more trouble than it's worth fixing.

2009-10-16linux-user: don't zero a buffer twicePaul Bolle1-1/+0
prepare_binprm() zeroes bprm->buf. That buffer is already zeroed in main() and hasn't been touched since so that is not necessary. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>

2009-06-16linux-user: implemented ELF coredump support for ARM targetMika Westerberg1-24/+26
When target process is killed with signal (such signal that should dump core) a coredump file is created. This file is similar than coredump generated by Linux (there are few exceptions though).
