The default is that such warnings are generated. This causes gcc to call the appropriate compiler for each file. If multiple flags are present, the last one is used. -g0¶ Don't generate any debug info (default). -gline-tables-only¶ Generate line number tables only. The default is that such warnings are not generated.
The use of `-gnatQ' forces generation of the `ALI' file. Although it would be technically possible to use sampling profiles for code coverage, sample-based profiles are too coarse-grained for code coverage purposes; it would yield poor results. The alternative would be to have cwd set to the source tree directory when launching gcc, to be able to specify source file arguments as file-only (the -o object file argument Exception handler containing only a reraise statement (raise with no operand) which has no effect.
This warning can also be turned on using `-gnatwa'. `-gnatw.R' Suppress warnings for object renaming function. In Ada 2012, it also activates all assertions defined in the RM as aspects: preconditions, postconditions, type invariants and (sub)type predicates. The two numbers in the function header specify how many total samples were accumulated in the function (first number), and the total number of samples accumulated in the prologue of the into the environment claims that "binary not found"..
Language and Target-Independent Features¶ Controlling Errors and Warnings¶ Clang provides a number of ways to control which code constructs cause it to emit errors and warning messages, and how they are Use of pragma Pack when all components are placed by a record representation clause. Note that these flags should appear after the corresponding profile flags to have an effect. This warning can also be turned on using `-gnatwa'. `-gnatwY' Disable warnings for Ada compatibility issues.

The warning string still appears, but the warning messages are counted as errors, and prevent the generation of an object file. But both calls to foo and bar are at the same source line, so a sample count at that line is not sufficient. This switch suppresses warnings for variables that are modified by using them as actuals for a call to a procedure with an out mode formal, where the resulting assigned value is
Description vrabcak 2008-04-17 14:52:00 UTC If I create project from existing code and then compile, output window doesn´t contain clickable links on compile errors, which makes error very hard to locate http://public.kitware.com/pipermail/cmake/2013-January/053116.html This switch causes all enumeration types to be considered as ordered, so that no warnings are given for comparisons or subranges for any type. `-gnatwv' Activate warnings on unassigned variables. Requires -flto. -fsanitize=safe-stack: safe stack protection against stack-based memory corruption errors. share|improve this answer answered Aug 15 '09 at 17:41 xcramps 1,04389 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign

Knowing that a function foo is called more frequently than another function bar helps the inliner. Reload to refresh your session. [CMake] Cmake absolute paths with gcc, __FILE__ , and logging Andreas Mohr andi at lisas.de Fri Jan 4 12:42:29 EST 2013 Previous message: [CMake] Cmake absolute The underlying motivation of the approach is that it is common for the same (and often large) header files to be included by multiple source files. have a peek at these guys As you make changes to your code, clang may no longer be able to use the profile data.
This switch suppresses warnings for unused entities and packages. Note that `-gnatwa' does not affect the setting of this warning option. `-gnatwH' Suppress warnings on hiding. Warnings are also generated if you are using the static mode of elaboration, and a pragma Elaborate is encountered.
In most cases, code "just works". Additionally, multiple raw profiles dumped from different processes that share a file system (can be on different hosts) will be automatically merged by the profiler runtime during the dumping. n is a decimal integer in the range of 1 to 999999 and limits the number of error or warning messages to be generated. This switch activates warnings for variables that are assigned (using an initialization value or with one or more assignment statements) but whose value is never read.
This switch suppresses warnings for indexing an unconstrained string parameter with a literal or S'Length. These switches are fully described in this section. It can also be generated from the binary or gcov formats using the llvm-profdata tool. check my blog The options are listed below. -f[no-]sanitize=check1,check2,...
Need to make our patterns more flexible. Compiling Using gcc This chapter discusses how to compile Ada programs using the gcc command. The rest of the introduction introduces some basic compiler terminology that is used throughout this manual and contains a basic introduction to using Clang as a command line compiler. A sampling profiler can generate a profile with very low runtime overhead, or you can build an instrumented version of the code that collects more detailed profile information.
