# Note that according to a benchmark run by Marc Feeley on May 2018,
|
|
# clang is 10x (with default settings) to 15% (with -O2) slower than GCC at compiling
|
|
# Gambit output, producing code that is 3x slower. IIRC the benchmarks from Gambit@30,
|
|
# the numbers were still heavily in favor of GCC in October 2019.
|
|
# Thus we use GCC over clang, even on macOS.
|
|
#
|
|
# Also note that I (fare) just ran benchmarks from https://github.com/ecraven/r7rs-benchmarks
|
|
# with Gambit 4.9.3 with -O1 vs -O2 vs -Os on Feb 2020. Which wins depends on the benchmark.
|
|
# The fight is unclear between -O1 and -O2, where -O1 wins more often, by up to 17%,
|
|
# but sometimes -O2 wins, once by up to 43%, so that overall -O2 is 5% faster.
|
|
# However, -Os seems more consistent in winning slightly against both -O1 and -O2,
|
|
# and is overall 15% faster than -O2. As for compile times, -O1 is fastest,
|
|
# -Os is about 29%-33% slower than -O1, while -O2 is about 40%-50% slower than -O1.
|
|
#
|
|
# Overall, -Os seems like the best choice, but I care more about compile-time,
|
|
# so I stick with -O1 (in the defaults above), which is also the default for Gambit.
