Rafaël Carré	45c7498f59	FS#11335 by me: make ARM assembly functions thumb-friendly ... We can't pop into pc on ARMv4t when using thumb: the T bit won't be modified if we are returning to a thumb function Code running on ARMv4t should use the new ldrpc / ldmpc macros instead of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc} No modification on pure ARM builds and ARMv5+ Note: USE_THUMB is currently never defined, no targets can currently be built with -mthumb, see FS#6734 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26756 a1c6a512-1295-4272-9138-f99709370657	2010-06-11 04:41:36 +00:00
Jens Arnold	64adb32cbf	Port the greylib blitting optimisation to m:robe 100. It's even more efficient on monochrome LCDs - about 20% ISR speedup. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26435 a1c6a512-1295-4272-9138-f99709370657	2010-05-31 20:13:27 +00:00
Jens Arnold	47d4c4739b	ARM asm LCD and ATA driver functions: Don't save r12 as it is a scratch reg. Saves a bit of stack and execution time. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21795 a1c6a512-1295-4272-9138-f99709370657	2009-07-11 23:43:44 +00:00
Daniel Stenberg	2acc0ac542	Updated our source code header to explicitly mention that we are GPL v2 or ... later.
