# Delete the builtin make rules, as if "make -r" was used.
.SUFFIXES:

# Ask make to not delete "intermediate" results, such as the .o in the chain
# .cc -> .o -> .so. Otherwise, during the first build, make considers the .o
# to be intermediate, and deletes it, but the newly-created ".d" files lists
# the ".o" as a target - so it needs to be created again on the second make.
# See commit fac05c95 for a longer explanation.
.SECONDARY:

# Deleting partially-build targets on error should be the default, but it
# isn't, for historical reasons, so we need to turn it on explicitly...

# this compilation, we pass to the compiler a special option (-MD) which
# causes it to also output a file with suffix ".d" listing the dependencies
# discovered during the compilation of that source file. From then on,
# on every compilation we "include" all the ".d" files generated in the

# Issue #867: Gcc 4.8.4 has a bug where it optimizes the trivial round-
# related functions incorrectly - it appears to convert calls to any
# function called round() to calls to a function called lround() -
# and similarly for roundf() and roundl().
# None of the specific "-fno-*" options disable this buggy optimization,
# unfortunately. The simplest workaround is to just disable optimization
# for the affected files.

# The dependencies on header files are automatically generated only after the

# the Makefile are special, in that they need to be created even *before* the
# first compilation. Moreover, some (namely version.h) need to perhaps be
# re-created on every compilation. "generated-headers" is used as an order-
# only dependency on C compilation rules above, so we don't try to compile
# C code before generating these headers.
