Added support for ARM v5 CPU info

[Mailaender]

Yet another undocumented patch from https://build.opensuse.org/package/show/Mono:Factory/mono-core. I can only guess what it does. Uploaded it here for review.

Hello! I'm the build bot for the Mono project. I need approval from a Mono team member to build this pull request. A team member should reply with "approve" to approve a build of this pull request, "whitelist" to whitelist this and all future pull requests from this contributor, or "build" to explicitly request a build, even if one has already been done. Contributors can ignore this message.

[Mailaender]

This is probably not necessary anymore.

We actually support ARM v4, so this isn't technically correct either.

(That said, I have no idea what kind of state our ARM v4 support is in since nobody seems to have v4 hardware anymore.)

This patch adds dead code, we should not be doing it.

Yeah, I read

    v5_supported = mono_hwcap_arm_is_v5;
    v6_supported = mono_hwcap_arm_is_v6;
    v7_supported = mono_hwcap_arm_is_v7;
    v7s_supported = mono_hwcap_arm_is_v7s;

some lines above and then decided to close this.

So I guess I can also throw away

• https://build.opensuse.org/package/view_file/Mono:Factory/mono-core/mono-arm-cpuinfo-v7.patch?expand=1
• https://build.opensuse.org/package/view_file/Mono:Factory/mono-core/mono-arm-cpuinfo-v5.patch?expand=1
• https://build.opensuse.org/package/view_file/Mono:Factory/mono-core/mono-arm-vfp.patch?expand=1

then?

[alexrp]

Yes - these hacks should no longer be necessary. We've sanitized the way the runtime detects CPU features on ARM.

Okay done. https://build.opensuse.org/package/rdiff/home:Mailaender:branches:Mono:Factory/mono-core?linkrev=base&rev=5
