From 15eaf6ffe3e117684a0e7b070c0a8754480d3fa3 Mon Sep 17 00:00:00 2001 From: Siddhesh Poyarekar Date: Sat, 22 Feb 2014 10:09:27 +0530 Subject: benchtests: Add new directive for benchmark initialization hook Add a new 'init' directive that specifies the name of the function to call to do function-specific initialization. This is useful for benchmarks that need to do a one-time initialization before the functions are executed. --- benchtests/README | 1 + benchtests/bench-skeleton.c | 3 +++ benchtests/scripts/bench.py | 7 ++++++- 3 files changed, 10 insertions(+), 1 deletion(-) (limited to 'benchtests') diff --git a/benchtests/README b/benchtests/README index 52a3cc2062..999d268cf8 100644 --- a/benchtests/README +++ b/benchtests/README @@ -62,6 +62,7 @@ one to add `foo' to the bench tests: and functions (specifically, this includes using "#include "source").
