*	FS#11335 by me: make ARM assembly functions thumb-friendly	Rafaël Carré	2010-06-11
\| \| \| \| \| \| \| \| \| \| \| \| \|	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

*	Use hand-written constants table on ARMv5+ for JPEG IDCT, and load four ↵	Andrew Mahone	2009-06-28
\| \| \| \| \| \|	16-bit constants at a time with ldrd. Not useful for ARMv4, since one load per constant would still be needed, and limited range of ldrsh would force multiple copies of table. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21535 a1c6a512-1295-4272-9138-f99709370657

\| \| \| \| \| \|	about inline asm, change loop condition to be a bit safer in case of bad values being passed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21349 a1c6a512-1295-4272-9138-f99709370657
*	Core JPEG decoder improvements:	Andrew Mahone	2009-06-19
	For >8-point vertical IDCT, transpose the coefficients while decoding them, so that the vertical IDCT can read in rows rather than columns. This improves speed a bit for this size even using the C IDCT. Remove inline ARM asm, replacing it with an external file containing pure asm IDCT functions. Add jpeg_ prefix to JPEG IDCT functions since some of them will now be visible globally. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21345 a1c6a512-1295-4272-9138-f99709370657
