Arm semihosting v2 implementation isn't complete

[Alexander Fedotov]

Hi all

I see that number of commits were dedicated to changes for Arm
Semihosting v2 specification that states:
ARM encourages semihosting callers to implement support for trapping
using HLT on A32 and T32 as a configurable option. ARM strongly
discourages semihosting callers from mixing the HLT and SVC mechanisms
within the same executable.

At the moment there is no HLT instruction used in libgloss/arm.

So the question is: is there any reason to not have HLT right now ?
