    • S/390: Fix failing RTL check in s390_canonicalize_comparison · 837ee1e0 
      The new sigfpe-eh.c fails with

    internal compiler error: RTL check: expected elt 0 type 'e' or 'u', have 'w' (rtx const_int)

This is most likely due to a typo: XEXP (*op1, 0) was used, when
XEXP (*op0, 1) was intended.  This did not cause any user-visible
problems, because reversed_comparison_code_parts ignores the
respective argument, and the release compiler is built without RTL
checks.

    • [AArch64] Add support for __jcvt intrinsic · e1d5d19e 
      This patch implements the __jcvt ACLE intrinsic [1] that maps down to the FJCVTZS [2] instruction from Armv8.3-a.
No fancy mode iterators or nothing. Just a single builtin, UNSPEC and define_insn and the associate plumbing.
This patch also defines __ARM_FEATURE_JCVT to indicate when the intrinsic is available.

    • [x86 testsuite] preserve full register across main · e4a8d4a7 
      This test uses a call-saved register as a global variable.  It
attempts to preserve its value across main, but only the lower int
part is preserved, which is not good enough for x86_64, when the
runtime that calls main() happens to hold something in the chosen
register that is not a zero-extension from the 32-bit value, and
rightfully expects the full register to remain unchanged when main()
returns.
