Re: [yocto] [Openembedded-architecture] Dropping armv5 and armv5e tunes in 2.7

But, just for informational purposes, I wanted to point out that I do have a couple ARM926EJ-S boards (i.MX233, LPC32xx) which are ARMv5TE which I am actively working with and maintaining. Therefore, thank you for keeping this one around. -- ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto

However, I was taking this time to find out if we can drop all the ones besides armv5te even if gcc supported it unless there were OE users who are still interested in supporting them and had devices running OE which need them > Non-thumb armv5/armv5e have been removed due to > "have no known implementations". > > Non-thumb armv4 support was deprecated in gcc 6 together with armv2/armv3, > but there are still people using recent gcc on StrongARM - which is > non-thumb armv4. OK, that's a fair point, however, in OE's case I only have reports from users with armv4t devices, but it we can keep the armv4 arm-only tunes around along with the arm-thumb v4 ones > > > Thanks > > -Khem > > cu > Adrian > > -- > >"Is there not promise of rain?"

Note that gcc 9 does *not* remove non-thumb armv4 support. Non-thumb armv5/armv5e have been removed due to "have no known implementations". Non-thumb armv4 support was deprecated in gcc 6 together with armv2/armv3, but there are still people using recent gcc on StrongARM - which is non-thumb armv4. > Thanks > -Khem cu Adrian -- "Is there not promise of rain?"
