It is considered slightly faster than the default mode[1], but on Windows it causes trouble when aborting the build, it leaves behind zero-sized object files which cause link error. See discussion in the bug-make mailing list[2].

# 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.
