The same program compiled with the `-gnatv' switch would generate: 3. when using cmake, which always uses full pathes). Controlling Code Generation¶ Clang provides a number of ways to control code generation. This is done at the task level since (it's simple, and...) I can't think of any downside to passing an absolute path. http://imagextension.com/gcc-error/gcc-error-message.php
The default is that such warnings are not given. Note that this offset should never be a negative number. soft soft snow Miles Bader, Dec 13, 2010 #8 Joshua Maurice Guest On Dec 12, 10:57 pm, Philipp Kraus <> wrote: > On 2010-12-12 23:21:17 +0100, Ian Collins said: > > More switches exist for GCC than those documented here, especially for specific targets.
I have hopen that anyone has the same problems. Note that when combined with -w (which disables all warnings), that flag wins. Relocatable PCH Files¶ It is sometimes necessary to build a precompiled header from headers that are not yet in their final, installed locations. Options to Emit Optimization Reports¶ Optimization reports trace, at a high-level, all the major decisions done by compiler transformations.
For example: $ clang -x c-header test.h -o test.h.pch $ cat test.c #include "test.h" $ clang test.c -o test In this example, clang will not automatically use the PCH file jump to error will work regardless of where in the directory tree waf is executed, which is ideal. Regardless of which kind of profiling you use, be careful to collect profiles by running your code with inputs that are representative of the typical behavior. This flag modifies the behavior of sanitizers in the cfi group to allow checking of cross-DSO virtual and indirect calls. -ffast-math¶ Enable fast-math mode.
This switch activates warnings on hiding declarations. Unable to find full path for "make" Unable to get $PATH. All warnings and style messages are treated as errors. `-gnatG=nn' List generated expanded code in source form. `-gnath' Output usage information. http://www.thecodingforums.com/threads/g-with-absolut-path-for-errors-warnings.739755/ I have template classes and a lot of "inline" declaration.
If this warning option is active, then record representation clauses should specify a contiguous layout, adding unused fill fields if needed. The Debug pragma causes procedure to be called. Previous message: [CMake] Cmake absolute paths with gcc, __FILE__ , and logging Next message: [CMake] Cmake absolute paths with gcc, __FILE__ , and logging Messages sorted by: [ date ] [ This option can be overridden on a case-by-case basis by putting an explicit “aligned” alignment on a struct, union, or typedef.
procedure a is separate; 4. Maybe it because cygwin directories are different with native windows directories? (/cygdrive/c prefix). The default is that such warnings are generated This warning can also be turned on using `-gnatwa'. `-gnatwI' Disable warnings on implementation units. Convert the collected profile data to LLVM's sample profile format.
Note that this option should be used only for compiling -- the code is likely to malfunction at run time. `-gnatjnn' Reformat error messages to fit on nn character lines `-gnatk=n' this content This switch activates warnings on component clauses in record representation clauses where the length given overrides that specified by an explicit size clause for the component type. For instance, when the inliner decides to inline function foo() into bar(), or the loop unroller decides to unroll a loop N times, or the vectorizer decides to vectorize For example, the use of default parameters in a convention C procedure is dubious because the C compiler cannot supply the proper default, so a warning is issued.
Evan Report message to a moderator Re: Cannot run program make: unknown reason - Problem with Remote C/C++ Projec [message #653091 is a reply to message #547456] Tue, See the diagnostics reference for a complete list of the warning flags that can be specified in this way. -Wno-foo¶ Disable warning "foo". -w¶ Disable all diagnostics. -Weverything¶ Enable all diagnostics. The switch `-gnat-p' may not be combined with any other switch. weblink First we briefly list all the switches, in alphabetical order, then we describe the switches in more detail in functionally grouped sections.
The default setting if no switch is given is 9999. This switch activates warnings for variables that are initialized but never modified, and then could be declared constants. This switch causes warning messages and style check messages to be treated as errors.
This is important for the profiler to be able to map instructions back to source line locations. $ clang++ -O2 -gline-tables-only code.cc -o code Run the executable under a sampling profiler. Note that these pragmas can also be controlled using the configuration pragmas Assertion_Policy and Debug_Policy. For example, if file `xyz.adb' is compiled with `-gnatl=.lst', then the output is written to file xyz.adb.lst. `-gnatU' This switch forces all error messages to be preceded by the unique string function1:total_samples:total_head_samples offset1[.discriminator]: number_of_samples [fn1:num fn2:num ... ] offset2[.discriminator]: number_of_samples [fn3:num fn4:num ... ] ...
For example, in this output: test.c:28:8: warning: extra tokens at end of #endif directive [-Wextra-tokens] #endif bad ^ // Passing -fno-diagnostics-fixit-info will prevent Clang from printing the "//" line at the Yes, my password is: Forgot your password? Newer Than: Search this thread only Search this forum only Display results as threads Useful Searches Recent Posts More... check over here For example, `-Wunused' activates back end warnings for entities that are declared but not referenced. `-Wuninitialized' Similarly, `-Wuninitialized' activates the back end warning for uninitialized variables.
Warnings may be set to ignored, warning, error, or fatal. Type conversion that converts an expression to its own type. Compiling Using gcc This chapter discusses how to compile Ada programs using the gcc command. Clang supports profile guided optimization with two different kinds of profiling.
Format For Printing -XML -Clone This Bug -Top of page First Last Prev Next This bug is not in your last search results. This switch disables warnings for a with of an internal GNAT implementation unit. `-gnatw.i' Activate warnings on overlapping actuals. Note that `-gnatwa' does not affect the setting of this warning option. `-gnatwD' Suppress warnings on implicit dereferencing. Pragma Assert and pragma Debug to be activated.
For example, the GNU C compiler is `cc1', and the Ada compiler is `gnat1'. This switch causes a full listing of the file to be generated. Using Sampling Profilers¶ Sampling profilers are used to collect runtime information, such as hardware counters, while your application executes. Scons can create on a > file the correct absolut path with drive letter on MS and leading slash > on unix systems, but Scons call the compiler only for the
up vote 2 down vote Sometimes I use a sed script for that (f.e. It is an error to read an invalid value, but the RM does not require run-time checks to detect such errors, except for some minimal checking to prevent erroneous execution (i.e. Also, again unlike switch `-gnatws', warnings suppressed by the use of switch `-gnatwA' can be individually turned back on. The format is described below.
See SanitizerStats for more details. -fsanitize-undefined-trap-on-error¶ Deprecated alias for -fsanitize-trap=undefined. -fsanitize-cfi-cross-dso¶ Enable cross-DSO control flow integrity checks. Using CMake for this purpose rather than having to create a couple dozen custom targets manually (which directly translates into creating a couple dozen project files manually) -- and the painful This option makes Clang print information about source ranges in a machine parsable format after the file/line/column number information. Join them; it only takes a minute: Sign up Can gcc be configured to not print out a full path in warning/error messages?
What happens if one brings more than 10,000 USD with them in the US?
