From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- libstdc++-v3/doc/html/manual/bk01pt03ch19s04.html | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 libstdc++-v3/doc/html/manual/bk01pt03ch19s04.html (limited to 'libstdc++-v3/doc/html/manual/bk01pt03ch19s04.html') diff --git a/libstdc++-v3/doc/html/manual/bk01pt03ch19s04.html b/libstdc++-v3/doc/html/manual/bk01pt03ch19s04.html new file mode 100644 index 000000000..8fc162b7c --- /dev/null +++ b/libstdc++-v3/doc/html/manual/bk01pt03ch19s04.html @@ -0,0 +1,18 @@ + + +Empirical Cost Model

Empirical Cost Model

+ Currently, the cost model uses formulas with predefined relative weights + for alternative containers or container implementations. For instance, + iterating through a vector is X times faster than iterating through a list. +

+ (Under development.) + We are working on customizing this to a particular machine by providing + an automated way to compute the actual relative weights for operations + on the given machine. +

+ (Under development.) + We plan to provide a performance parameter database format that can be + filled in either by hand or by an automated training mechanism. + The analysis module will then use this database instead of the built in. + generic parameters. +
