CPUFeatures plug-in

Author: LoRd MuldeR (talk, contrib)

This very simple plug-in can detect the supported CPU features (MMX, SSE, AVX, etc) at runtime.

It is based on CPU detection code from the x264 project.

Example

How to use the CPUFeatures plug-in:

!include "CPUFeatures.nsh"
 
; Get CPU flags (this is for debugging!)
Section
	${CPUFeatures.GetFlags} $0
	DetailPrint "CPU Flags: $0"
SectionEnd
 
; Get all supported features + vendor name
Section
	${CPUFeatures.GetFeatures} $0
	DetailPrint "CPU Features: $0"
 
	${CPUFeatures.GetVendor} $0
	DetailPrint "CPU Vendor: $0"
SectionEnd
 
; Check individual feature flags
; Find a list of supported feature flags in CPUFeatures.nsh!
Section
	${CPUFeatures.CheckFeature} "MMX1" $0
	DetailPrint "Has MMX: $0"
 
	${CPUFeatures.CheckFeature} "SSE1" $0
	DetailPrint "Has SSE: $0"
 
	${CPUFeatures.CheckFeature} "SSE2" $0
	DetailPrint "Has SSE2: $0"
 
	${CPUFeatures.CheckFeature} "SSE3" $0
	DetailPrint "Has SSE3: $0"
 
	${CPUFeatures.CheckFeature} "SSSE3" $0
	DetailPrint "Has SSSE3: $0"
 
	${CPUFeatures.CheckFeature} "SSE4.2" $0
	DetailPrint "Has SSE4.2: $0"
 
	; Next call is supposed to fail!
	${CPUFeatures.CheckFeature} "SSE7" $0
	DetailPrint "Has SSE7: $0"
SectionEnd
