Enabled at level -O0. This flag is enabled by default at -O and higher. -ftree-prePerform partial redundancy elimination (PRE) on trees. Check This Out

It does, however, solve the immediate problem (not being able to install certain gems), and is sufficient untill the maintainers of the gems update their projects to not violate the treat-warnings-as-errors Strip mining splits a loop into two nested loops. Reordering is done by the linker so object file format must support named sections and linker must place them in a reasonable way. This allows a loop containing a load/store sequence to be changed to a load outside the loop, and a copy/store within the loop. http://clang.debian.net/status.php?version=3.4.2&key=UNKNOWN_ARG

As compared to -O, this option increases both compilation time and the performance of the generated code. -O2 turns on all optimization flags specified by -O. For example, given a loop like: DO I = 1, N A(I) = A(I) + C ENDDO loop strip mining will transform the loop as if the user had written: DO This option affects only the profile data generated by -fprofile-generate, -ftest-coverage, -fprofile-arcs and used by -fprofile-use and -fbranch-probabilities and its related options.

BSD nm checking whether ln -s works... If the value is greater or equal to 10, the dump file will be stderr as if the value were n minus 10. -fdelayed-branchIf supported for the target machine, attempt to Enabled at levels -O2, -O3. -funit-at-a-timeThis option is left for compatibility reasons. -funit-at-a-time has no effect, while -fno-unit-at-a-time implies -fno-toplevel-reorder and -fno-section-anchors. ivancevich commented Nov 8, 2015 I'm almost there: ➜ bin git:(master) pwd /usr/local/bin ➜ bin git:(master) musikernel2.py sys.argv == ['/usr/local/bin/musikernel2.py'] /usr/local/lib/musikernel2/pydaw/python ICON_PATH = '/usr/local/share/pixmaps/musikernel2.png' install prefix: /usr/local BIN_PATH == None Using

This is especially useful on machines with a relatively small number of registers and where memory load instructions take more than one cycle. For C (and C++) this means that overflow when doing arithmetic with signed numbers is undefined, which means that the compiler may assume that it will not happen. o checking whether we are using the GNU C compiler... https://kaspermunck.github.io/2014/03/fixing-clang-error/ I'll begin distributing the Mac OS X port using Homebrew or an installer package when MusiKernel 2 is officially released.

You will not be able to use gprof on all systems if you specify this option and you may have problems with debugging if you specify both this option and -g. This is implemented by using special subsections .text.hot for most frequently executed functions and .text.unlikely for unlikely executed functions. c++ -c src/import.cpp -O3 -ffast-math -fprefetch-loop-arrays -fsingle-precision-constant -funroll-loops -Wall -Isrc -I../include -fstrength-reduce -fstrict-aliasing -finline-functions -o src/import.o clang: warning: optimization flag '-fprefetch-loop-arrays' is not supported clang: warning: optimization flag '-fsingle-precision-constant' is not GCC (and every other command line tool really) errors > on unknown options. > > We do try to ignore GCC options that are safe to ignore, so a patch >

This is similar to the constant propagation pass, but instead of values, ranges of values are propagated. http://lists.llvm.org/pipermail/cfe-dev/2014-January/034765.html darwin15.0.0 dyld checking how to hardcode library paths into programs... Currently the optimizations include specialization of division operation using the knowledge about the value of the denominator. -frename-registersAttempt to avoid false dependencies in scheduled code by making use of registers left no checking for awk...

The default value, 0, implies that GCC will select the most appropriate size itself. his comment is here no checking whether the g++ linker (/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld) supports shared libraries...

The algorithm argument should be priority or CB. this contact form Normally this option is used to keep the compiler from expanding any functions inline.

The default is -ffunction-cse -fno-zero-initialized-in-bssIf the target supports a BSS section, GCC by default puts variables that are initialized to zero into BSS. yes checking for clang option to produce PIC... -fno-common -DPIC checking if clang PIC flag -fno-common -DPIC works... This command line option will be used to specify the default state for FENV_ACCESS. -frtl-abstract-sequencesIt is a size optimization method.

Use -fmudflapir, in addition to -fmudflap or -fmudflapth, if instrumentation should ignore pointer reads. We recommend upgrading to the latest Safari, Google Chrome, or Firefox. This option implies -pthread, and thus is only supported on targets that have support for -pthread. -ftree-sraPerform scalar replacement of aggregates. This optimization will most benefit processors with lots of registers.

yes checking for memory.h...

Perhaps you should add the directory containing `alsa.pc' to the PKG_CONFIG_PATH environment variable No package 'alsa' found clang src/main.o -lpthread -lportmidi -lportaudio -shared -L/usr/local/Cellar/libsndfile/1.0.25/lib -L/usr/local/Cellar/fftw/3.3.4_1/lib -lsndfile -lfftw3f -lm -L/usr/local/Cellar/liblo/0.28/lib -llo -o Embed Embed this gist in your website. Can my employer see what I do on the internet when I am connected to the company network? The guards are initialized when a function is entered and then checked when the function exits.

Transposing is enabled only if profiling information is available. -ftree-sinkPerform forward store motion on trees. This includes functions that call alloca, and functions with buffers larger than 8 bytes. immediate checking how to run the C++ preprocessor... The machine-description macro FRAME_POINTER_REQUIRED controls whether a target machine supports this flag.

If you want to force the compiler to check if the variable was referenced, regardless of whether or not optimization is turned on, use the -fno-keep-static-consts option. -fmerge-constantsAttempt to merge identical This flag is enabled by default at -O and higher. -ftree-dsePerform dead store elimination (DSE) on trees. This avoids the instructions to save, set up and restore frame pointers; it also makes an extra register available in many functions. This option requires that both -fno-signed-zeros and -fno-trapping-math be in effect.

Note that if you are not optimizing, no functions can be expanded inline. -finline-small-functionsIntegrate functions into their callers when their body is smaller than expected function call code (so overall size Why are rotational matrices not commutative? yes checking whether the shell understands "+="...
