From: José Fonseca Date: Thu, 26 Jan 2012 19:08:32 +0000 (+0000) Subject: Allow to use call sets instead of call numbers / frequencies. X-Git-Tag: 2.0_alpha^2~341 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=225193db0f50a8f3a1d59d7cff351c9be31e8044;p=tools%2Fapitrace.git Allow to use call sets instead of call numbers / frequencies. Inspired on Carl Worth's --call=Range option, but: - with the extra machinery to allow semantic divisors, in addition to numeric ones. - allows reading the call numbers of a text file. --- diff --git a/CMakeLists.txt b/CMakeLists.txt index 24e2afc..22f7677 100755 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -271,6 +271,7 @@ else () endif () add_library (common STATIC + common/trace_callset.cpp common/trace_dump.cpp common/trace_file.cpp common/trace_file_read.cpp diff --git a/README.markdown b/README.markdown index 0a1bceb..38dfa5e 100644 --- a/README.markdown +++ b/README.markdown @@ -64,6 +64,34 @@ Advanced command line usage =========================== +Call sets +--------- + +Several tools take `CALLSET` arguments, e.g: + + apitrace dump --calls CALLSET foo.trace + glretrace -S CALLSET foo.trace + +The call syntax is very flexible.
