No description
conditions this may lead to massive slowdown of floating point operations when underflows or denormals are encountered. In particular, this problem was observed with the soxr resampler after applying https://gitlab.freedesktop.org/pulseaudio/pulseaudio/merge_requests/120 Therefore this patch adds -ffast-math to the link flags of the pulseaudio daemon. Linking with -ffast-math adds a procedure set_fast_math() to the startup code of the daemon. On x86, the procedure sets bit 6 and 15 of the mxcsr register. When these bits are set, denormals and results of underflowing operations are truncated to 0. |

HACKING:
In order to run pulseaudio from the build dir __OPTIMIZE__ should be
disabled (look at src/pulsecore/core-util.h::pa_run_from_build_tree()),
this can be done by passing "CFLAGS=-O0" to the configure script:
./autogen.sh
CFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3" ./configure
make
./src/pulseaudio -n -F src/default.pa -p $(pwd)/src/
