a0e1befb57 On MIPS handle got16 relocations to local symbols in an ABI-compliant 
way.

c36c73f681 Add support for a new magic symbol _gp_disp on mips to handle PIC 
binaries.

6f4a19f59f Use $t9 for indirect calls from asm to C as PIC ABI requires. 2013-11-22 04:45:05 +01:00

0d8f04cd83 Remove -march=mips3 from TARGET_CCASFLAGS as it creates linking problem 
when rest of GRUB is compiled for hisher stepping. Instead use
	.set mips3/.set mips1 around cache and sync opcodes.

4906052019 Unify GOT/trampoline handling between PPC, MIPS and IA64 as they 
do essentially the same thing, do it in similar way.

7960d3e182 * grub-core/kern/x86_64/efi/startup.S (_start): Align the stack to a 
16-byte boundary, as required by the x86-64 ABI, before calling
	grub_main.  In some cases, GCC emits code that assumes this
	alignment, which crashes if not aligned.  The EFI firmware is also
	entitled to assume that stack alignment without checking.

45bf8b3a75 * grub-core/kern/mm.c (grub_real_malloc): Decrease cut-off of moving the 
pointer to 32K. This is the size of cache element which is the most
	common allocation >1K. This way the pointer is always around blocks
	of 32K and so we keep performance while decreasing fragmentation.

39ff43c579 * grub-core/kern/mm.c (grub_real_malloc): Don't update the pointer to 
current memory when allocating large chunks. This significantly
	decreases memory fragmentation.

cd46aa6cef Rewrite grub-install, grub-mkrescue, grub-mkstandalone and grub-mknetdir 
the function of these files exceeds what can be sanely handled in shell
	in posix-comaptible way. Also writing it in C extends the functionality
	to non-UNIX-like OS and minimal environments.

593865b907 arm: fix u-boot port syscall interface va_arg handling 
Commit c9cd02c broke the u-boot syscall API for va_args that spill over
to the stack, causing the disk support to stop working. This patch
resolves the problem, while keeping the new, cleaner transition_space
handling.

6fcec43954 Replace libgcc version of ctz with our own. 
On upcoming arm64 port libgcc ctz* are not usable in standalone
	environment. Since we need ctz* for this case and implementation is
	in C we may as well use it on all concerned platforms.
