User space atomic ops on ARMv5 and earlierUser space atomic ops on ARMv5 and earlierPosted Jan 13, 2009 22:18 UTC (Tue) by endecotp (guest, #36428)In reply to: User space atomic ops on ARMv5 and earlier by npitre Parent article: ARM SoC launched with Linux support (Linux Devices)
I've just done a quick test and it looks like gcc emits a function call when you invoke __sync_* for ARM. So presumably it would be possible to write a small library of things with the right names that calls the kernel helper code. Then near-optimal portable code would be possible.
Maybe someone has already done this....
