Subject: Treat model == 0x4f as Broadwell
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dc04bc843188dff973f0a9a758d25217fad66444;p=gcc.git

Treat model == 0x4f as Broadwell

From Intel SDM Vol 3:

Table 35-29 lists MSRs that are common to processors based on the
Broadwell microarchitectures (including CPUID signatures 06_3DH,
06_47H, 06_4FH, and 06_56H).

	* config/i386/driver-i386.c (host_detect_local_cpu): Treat
	model == 0x4f as Broadwell.
