FS#5226 - Remove icode and long-calls from PP502x iPod builds
The attached patch removes all code from IRAM on the PP502x ipods (but leaves it there for the 3g) and removes the -mlong-calls GCC option. This reduces the size of rockbox.ipod from 376692 bytes to 323704 bytes.
Some brief testing with an MP3 file on my 4G Color ipod gave about 74% boost ratio with CVS Rockbox, 75% boost with this patch, and about 90% boost if I disabled the use of IRAM completely, but more thorough testing would be useful before deciding if this is to be committed to CVS.

<linuxstb> I think amiconn's
fixes (which IIUC have removed most long
calls) probably make it obsolete.

FLAC with EQ on, gained just 1% boost with this patch.
MOD (without EQ) also gained 1% with patched applied.
running on 5g
works for my nano
Needs updating if this still works… or is it in SVN already?
This patch is out of date, but I just tested the attached updated version on my H10 with a test FLAC file. With the code in IRAM, i get 393.20% realtime. Moving the code out of IRAM using the attached patch, I get 392.25% realtime.
Dave, are you going to bring up to date and commit?
