Ayke van Laethem	8cd2a462b9	runtime: remove the asyncScheduler constant ... There is no reason to specialize this per chip as it is only ever used for JavaScript. Not only that, it is causing confusion and is yet another quirk to learn when porting the runtime to a new microcontroller.	2021-05-08 23:08:12 +02:00
Ayke van Laethem	f79e66ac2e	cortexm: disable FPU on Cortex-M4 ... On some boards the FPU is already enabled on startup, probably as part of the bootloader. On other chips it was enabled as part of the runtime startup code. In all these cases, enabling the FPU is currently unsupported: the automatic stack sizing of goroutines assumes that the processor won't need to reserve space for FPU registers. Enabling the FPU therefore can lead to a stack overflow. This commit either removes the code that enables the FPU, or simply disables it in startup code. A future change should fully enable the FPU so that operations on float32 can be performed by the FPU instead of in software, greatly speeding up such code.	2021-04-24 18:41:40 +02:00
