From 47623aabb4832d3d217faa1a9938bb7a6e4341c3 Mon Sep 17 00:00:00 2001 From: Martin Braun Date: Fri, 8 Jan 2021 13:23:17 +0100 Subject: lib: Use const-ref in for loops instead of const-copy This is potentially a performance issue, even though it doesn't have a big impact in this context. Clang will warn about it, and this fixes the compiler warning. --- host/lib/usrp/dboard/db_tvrx.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'host/lib/usrp/dboard/db_tvrx.cpp') diff --git a/host/lib/usrp/dboard/db_tvrx.cpp b/host/lib/usrp/dboard/db_tvrx.cpp index 02fed018c..c9a940d15 100644 --- a/host/lib/usrp/dboard/db_tvrx.cpp +++ b/host/lib/usrp/dboard/db_tvrx.cpp @@ -158,7 +158,7 @@ static const boost::array tvrx_gains_volts = {{0.8, static uhd::dict get_tvrx_gain_ranges(void) { double rfmax = 0.0, rfmin = FLT_MAX; - for (const std::string range : tvrx_rf_gains_db.keys()) { + for (const std::string& range : tvrx_rf_gains_db.keys()) { double my_max = tvrx_rf_gains_db[range].back(); // we're assuming it's monotonic double my_min = tvrx_rf_gains_db[range].front(); // if it's not this is wrong wrong wrong -- cgit v1.2.3
