Reland "[FPEnv][Clang][Driver] Disable constrained floating point on targets lacking support." We currently have strict floating point/constrained floating point enabled for all targets. Constrained SDAG nodes get converted to the regular ones before reaching the target layer. In theory this should be fine. However, the changes are exposed to users through multiple clang options already in use in the field, and the changes are _completely_ _untested_ on almost all of our targets. Bugs have already been found, like "https://bugs.llvm.org/show_bug.cgi?id=45274". This patch disables constrained floating point options in clang everywhere except X86 and SystemZ. A warning will be printed when this happens.

.. option:: -frecord-command-line, -fno-record-command-line, -frecord-gcc-switches
Implement -frecord-command-line (-frecord-gcc-switches) Implement options in clang to enable recording the driver command-line in an ELF section. Implement a new special named metadata, llvm.commandline, to support frontends embedding their command-line options in IR/ASM/ELF. This differs from the GCC implementation in some key ways: * In GCC there is only one command-line possible per compilation-unit, in LLVM it mirrors llvm.ident and multiple are allowed. * In GCC individual options are separated by NULL bytes, in LLVM entire command-lines are separated by NULL bytes. The advantage of the GCC approach is to clearly delineate options in the face of embedded spaces. The advantage of the LLVM approach is to support merging multiple command-lines unambiguously, while handling embedded spaces with escaping.

Recommit #2 "[Driver] Default to -fno-common for all targets" After a first attempt to fix the test-suite failures, my first recommit caused the same failures again. I had updated CMakeList.txt files of tests that needed -fcommon, but it turns out that there are also Makefiles which are used by some bots, so I've updated these Makefiles now too.

Enable stack protectors for some functions vulnerable to stack smashing. This uses a loose heuristic which considers functions vulnerable if they contain a char (or 8bit integer) array or constant sized calls to alloca , which are of greater size than ssp-buffer-size (default: 8 bytes). All variable sized calls to alloca are considered vulnerable. A function with a stack protector has a guard value added to the stack frame that is checked on function exit. The guard value must be positioned in the stack frame such that a buffer overflow from a vulnerable variable will overwrite the guard value before overwriting the function's return address. The reference stack guard value is stored in a global variable.

Generate branches with extended addressability, usually via indirect jumps.
[X86] Add Indirect Thunk Support to X86 to mitigate Load Value Injection (LVI) This pass replaces each indirect call/jump with a direct call to a thunk that looks like: lfence jmpq *%r11 This ensures that if the value in register %r11 was loaded from memory, then the value in %r11 is (architecturally) correct prior to the jump. Also adds a new target feature to X86: +lvi-cfi ("cfi" meaning control-flow integrity) The feature can be added via clang CLI using -mlvi-cfi. This is an alternate implementation to https://reviews.llvm.org/D75934 That merges the thunk insertion functionality with the existing X86 retpoline code.

[Driver][CodeGen] Add -mprefer-vector-width driver option and attribute during CodeGen. This adds a new command line option -mprefer-vector-width to specify a preferred vector width for the vectorizers. Valid values are 'none' and unsigned integers. The driver will check that it meets those constraints. Specific supported integers will be managed by the targets in the backend. Clang will take the value and add it as a new function attribute during CodeGen. This represents the alternate direction proposed by Sanjay in this RFC: http://lists.llvm.org/pipermail/llvm-dev/2017-November/118734.html The syntax here matches gcc, though gcc treats it as an x86 specific command line argument. gcc only allows values of 128, 256, and 512. I'm not having clang check any values. Differential Revision: https://reviews.llvm.org/D40230 llvm-svn: 320419

[x86][seses] Add clang flag; Use lvi-cfi with seses This patch creates a clang flag to enable SESES. This flag also ensures that lvi-cfi is on when using seses via clang. SESES should use lvi-cfi to mitigate returns and indirect branches. The flag to enable the SESES functionality only without lvi-cfi is now -x86-seses-enable-without-lvi-cfi to warn users part of the mitigation is not enabled if they use this flag. This is useful in case folks want to see the cost of SESES separate from the LVI-CFI. Reviewed By: sconstab Differential Revision: https://reviews.llvm.org/D79910
