If you compile with this flag and your program mysteriously crashes after "main()" has completed, you may have an object that is being destroyed twice because two definitions were merged.

Currently equivalent to '-Wformat -Wformat-nonliteral -Wformat-security'. -WnonnullEnable warning about passing a null pointer for arguments marked as requiring a non-null value by the nonnull function attribute. '-Wnonnull' is included in '-Wall' https://gcc.gnu.org/onlinedocs/gnat_ugn/Output-and-Error-Message-Control.html
Warnings from system headers are normally suppressed, on the assumption that they usually do not indicate real problems and would only make the compiler output harder to read. The user supplied compilation step can then add in an additional preprocessing step after normal preprocessing but before compiling. This option was first supported in GCC 4.3. The unary plus operator.
The name gnu9x is deprecated. This allows the compiler to correctly set edge weights into foo and bar. Options to Emit Optimization Reports¶ Optimization reports trace, at a high-level, all the major decisions done by compiler transformations. For diffing large templated types, this option will cause Clang to display the templates as an indented text tree, one argument per line, with differences marked inline.
For example, the -c option says not to run the linker. Gcc Options For more info about standard options that are recognized by the compiler, read the official manual. Warnings may be set to ignored, warning, error, or fatal. These warnings are made optional because GCC is not smart enough to see all the reasons why the code might be correct despite appearing to have an error.
This means to use the most expressive format available, including GDB extensions if at all possible. -gstabsProduce debugging information in stabs format. -gstabs+Produce debugging information in stabs format, using GNU extensions Macro parameters that appear within string literals in the macro body. Storage-class specifiers like static are not the first things in a declaration. This option is accepted and ignored by GCC versions 4.1.3 up to but not including 4.3.
Version 2 is the version of the C ++ ABI that first appeared in G++ 3.4. This is equivalent to '-fno-freestanding'. Colorgcc Copies published by the Free Software Foundation raise funds for GNU development. Among the consequences of these changes are that static data members of the same type with the same name but defined in different shared objects will be different, so changing one
GCC recognizes files with these names and compiles them as C ++ programs even if you call the compiler the same way as for compiling C programs (usually with the name The main checks are: -fsanitize=address: AddressSanitizer, a memory error detector. -fsanitize=thread: ThreadSanitizer, a data race detector. -fsanitize=memory: MemorySanitizer, a detector of uninitialized reads. Note that Clang will never emit type information for types that are not referenced at all by the program. -fno-standalone-debug¶ On Darwin -fstandalone-debug is enabled by default. They are only meant to implement GCC's semantics with respect to profile creation and use. -fprofile-generate[=]¶ The -fprofile-generate and -fprofile-generate= flags will use an alterantive instrumentation method for profile
E.g., so that the resulting executable can find the beginning of that section and/or make assumptions based on that. This requires building a special instrumented version of the code and has some runtime overhead during the profiling, but it provides more detailed results than a sampling profiler. Also, they do not occur for structures, unions or arrays, even when they are in registers. n is a decimal integer in the range of 1 to 999 and limits the number of error messages to be generated.
In the table below, only one of the forms is listed: the one you typically will use. This switch causes a full listing of the file to be generated. null | >>> missing ";" 6.
Note that it does not suppress warnings from the gcc back end.
The effect of this setting is to write long-format error messages to stdout (the standard output file. For example, if you do want to compare pointers to a particular inline method, you might mark it as having default visibility. This avoids the instructions to save, set up and restore frame pointers; it also makes an extra register available in many functions. For example, if you want to build a precompiled header for the header mylib.h that will be installed into /usr/include, create a subdirectory build/usr/include and place the header
When given a directory name, it generates the profile file default_%m.profraw in the directory named dirname if specified. deeply embedded) where a trap cannot be properly handled, or when some custom behavior is desired. -ftls-model=[model]¶ Select which TLS model to use. Many options have multi-letter names; therefore multiple single-letter options may not be grouped: '-dr' is very different from '-d -r'. Either the range or the replacement string may be empty (representing strict insertions and strict erasures, respectively).

By default, an included file is treated as a system header if it is found in an include path specified by -isystem, but this can be overridden in several ways. For those languages that do not support IMA this option will be ignored, and the compiler will be invoked once for each source file in that language. share|improve this answer answered Mar 15 '13 at 6:43 Paul Fultz II 10.1k63943 3 That's nice -- it does make the messages a bit easier to follow. For machines which must pop arguments after a function call, the compiler normally lets arguments accumulate on the stack for several function calls and pops them all at once.
You may want to use the -fno-gnu-keywords flag instead, which has the same effect. Note that the tigcc frontend defaults to DWARF 2 debugging information instead, see Options Available in the Command Line Compiler. However, Clang's column number is much more accurate, pointing at the problematic format specifier, rather than the ) character the parser had reached when the problem was detected. This switch causes GNAT to generate the brief format error messages to stderr (the standard error file) as well as the verbose format message or full listing (which as usual is
See Options Controlling the Preprocessor for more information. -no-integrated-cppPerforms a compilation in two passes: preprocessing and compiling. When you compile C ++ programs, you may specify many of the same command-line options that you use for compiling programs in any language; or command-line options meaningful for C and If you are using Linux Perf to generate sampling profiles, you can use the conversion tool create_llvm_prof described in the previous section. Next:Warning Message Control, Previous:Alphabetical List of All Switches, Up:Compiler Switches 4.3.2 Output and Error Message Control The standard default format for error messages is called 'brief format'.
Generally, this only occurs to those living on the bleeding edge.
