Commit 61f25daa8d1b69dd5138facd5d57a8e3dfa0c5cc by alexandros.lamprineas [ARM][CMSE] Clear the secure fp-registers when using softfp abi. When expanding the non-secure call instruction we are emiting code to clear the secure floating-point registers only if the targeted architecture has floating-point support. The potential problem is when the source code containing non-secure calls are built with -mfloat-abi=soft but some other part of the system has been built with -mfloat-abi=softfp (soft and softfp are compatible as they use the same procedure calling standard). In this case floating-point registers could leak to non-secure state as the non-secure won't have cleared them assuming no floating point has been used.

Commit 1bd5ea968e9262a09512a64bca1624818640bc5b by alexandros.lamprineas [ARM] Mitigate the cve-2021-35465 security vulnurability. Recently a vulnerability issue is found in the implementation of VLLDM instruction in the Arm Cortex-M33, Cortex-M35P and Cortex-M55. If the VLLDM instruction is abandoned due to an exception when it is partially completed, it is possible for subsequent non-secure handler to access and modify the partial restored register values. This vulnerability is identified as CVE-2021-35465. The mitigation sequence varies between v8-m and v8.1-m as follows: v8-m.main --------- mrs r5, control tst r5, #8 /* CONTROL_S.SFPA / it ne .inst.w 0xeeb00a40 / vmovne s0, s0 / 1: vlldm sp / Lazy restore of d0-d16 and FPSCR. / v8.1-m.main ----------- vscclrm {vpr} / Clear VPR. / vlldm sp / Lazy restore of d0-d16 and FPSCR. */ More details on developer.arm.com/support/arm-security-updates/vlldm-instruction-security-vulnerability Differential Revision: https://reviews.llvm.org/D109157

Commit ab41eef9aca3ad5e9321e045a57d36e288a75d17 by bjorn.a.pettersson [NewPM] Use a separate struct for ModuleMemorySanitizerPass Split MemorySanitizerPass into MemorySanitizerPass (as a function pass) and ModuleMemorySanitizerPass (as a module pass). Main reason is to make sure that we have a unique mapping from ClassName to PassName in the new passmanager framework, making it possible to correctly identify the passes when dealing with options such as -print-after and -print-pipeline-passes. This is a follow-up to D105006 and D105007.

Commit a773db7d76222ccf4365979e01dd582fd2b5b3df by aschwaighofer Add a command-line flag to control the Swift extended async frame info. Introduce a new command-line flag `-swift-async-fp={auto\|always\|never}` that controls how code generation sets the Swift extended async frame info bit. There are three possibilities: * `auto`: which determines how to set the bit based on deployment target, either statically or dynamically via `swift_async_extendedFramePointerFlags`. * `always`: the default, always set the bit statically, regardless of deployment target. * `never`: never set the bit, regardless of deployment target.
