The Intel whitepaer[1] recommends using the RDSEED over RDRAND whenever present. libstdc++ from GCC 10 will also use it in std::random_device. [ChangeLog][QtCore][QRandomGenerator] The system() random generator will now use the RDSEED instruction on x86 processors whenever available as the first source of random data. It will fall back to RDRAND and then to the system functions, in that order.

# This file is used as a basis for the following compilers:
|
|
#
|
|
# - The GNU C++ compiler (g++)
|
|
# - LLVM
|
|
# - Clang
|
|
#
|
|
# Platform-specific options shared by these compilers are put into:
|
|
#
|
|
# - gcc-base-mac.conf
|
|
# - gcc-base-unix.conf
|
|
#
|
|
# These base files are then combined with configurations for each compiler:
|
|
#
|
|
# - g++-base.conf
|
|
# - g++-macx.conf
|
|
# - g++-unix.conf
|
|
# - llvm.conf
|
|
# - clang.conf
|
|
#
|
|
# The combination happens in the top level mkspec, by including a platform-
|
|
# specific version of the base-file, for example gcc-base-mac.conf, and then
|
|
# a (possibly platform-specific) version of the actual compiler configuration,
|
|
# for example g++-macx.conf.
|
|
#
|
|
# If you are making changes to any of these files, please consider the
|
|
# possible effect it may have due to these include-rules, and whether it
|
|
# might make more sense to share the rule or make it more specific.
|
|
#
|
|
# To verify that your change has the desired effect on the final configuration
|
|
# you can use the manual test in tests/manual/mkspecs.
