If the - options form is used, options is a list of - separated options which control the details of the dump. A diagnostic has a "kind". Note that all modules in a program must be compiled with the same value for this option. This option requires that both -fno-signed-zeros and -fno-trapping-math be in effect. This typically results in the smallest code size, and is enabled by default for -Os or -O0. Fobjc-direct-dispatch Allow fast jumps to the message dispatcher. The default value is 1. aarch64-double-recp-precision The number of Newton iterations for calculating the reciprocal for double type. This includes installing on Windows, Mac OS X, and Linux, the command-line tools using ECMA Script 2015 features in, and the npm package management system. This is useful if you need to make sure that your Objective-C code can be compiled with older versions of GCC. Ms Generate code for the H8S. This option conflicts with -mslow-flash-data. Mblock-compare-inline-loop-limit= num Generate an inline expansion using loop code for all block compares that are less than or equal to num bytes, but greater than the limit for non-loop inline block compare expansion. Dialect needs to be explicitly supplied as of v4.0.0 4. Usually used with -fdump-rtl-expand.
Loop-interchange-max-num-stmts The maximum number of stmts in a loop to be interchanged. Used by Centrino notebooks. Mcall-linux On System V. 4 and embedded PowerPC systems compile code for the Linux-based GNU system. Mlong-double-64 -mlong-double-128 These switches control the size of "long double" type. Fvtable-verify=preinit causes them to be built before shared libraries have been loaded and initialized. Mkernel= version This specifies the minimum version of the kernel that will run the compiled program. Mfull-regs Use full-set registers for register allocation. Dialect needs to be explicitly supplied as of v4.0.0 used. This option is enabled by default but only takes effect when the selected architecture is known to support bonding. Mno-cache-volatile -mcache-volatile Volatile memory access bypass the cache using the I/O variants of the load and store instructions.
MicroBlaze Options -msoft-float Use software emulation for floating point (default). Fobjc-std=objc1 Conform to the language syntax of Objective-C 1. The flag has no effect for functions explicitly declared inline (where it is never allowed for interposition to change semantics) and for symbols explicitly declared weak. As new Intel processors are deployed in the marketplace, the behavior of this option will change. Flinker-output= type This option controls code generation of the link-time optimizer. Where none of -mtune=, -mcpu= or -march= are specified, the code is tuned to perform well across a range of target processors. If you receive a linker error message that saying you have overflowed the available TOC space, you can reduce the amount of TOC space used with the -mno-fp-in-toc and -mno-sum-in-toc options. The default is to use 16-bit offsets. The choices for architecture-type are v3, v8 and v10 for respectively ETRAX 4, ETRAX 100, and ETRAX 100 LX. The JSON is emitted as one line, without formatting; the examples below have been formatted for clarity. Error: Dialect needs to be explicitly supplied as of v4.0.0 · Issue #1068 · sequelize/cli ·. Enabled at levels -O2, -O3, -Os, however the option is disabled if generated code will be instrumented for profiling (-p, or -pg) or if callee's register usage cannot be known exactly (this happens on targets that do not expose prologues and epilogues in RTL). The second number is "system time", time spent executing operating system routines on behalf of the program. This model works only when the program runs in privileged mode and is only suitable for single-core systems.
C++ only) Subscripting an array that has been declared "register". These instructions may prefetch data, which is not safe to do if accessing an I/O register. Here is one example of how this can happen: { int x; switch (y) { case 1: x = 1; break; case 2: x = 4; break; case 3: x = 5;} foo (x);} If the value of "y" is always 1, 2 or 3, then "x" is always initialized, but GCC doesn't know this. To be fully SVR4 ABI-compliant at the cost of some performance loss, specify -mno-app-regs. This is enabled by default. However, only aggregates larger than eight bytes are passed by hidden reference and the option provides better compatibility with OpenMP. The generally leads to short and fast code, but the number of different data items that can be addressed is limited. To avoid confusion, the ISO 10646 standard sets out some normalization rules which when applied ensure that two sequences that look the same are turned into the same sequence. It conflicts with -mword-relocations. Dialect needs to be explicitly supplied as of v4.0.0 10. The default is to issue a warning for each extra fast interrupt handler found, as the RX only supports one such interrupt.
Ev56 21164a Schedules as an EV5 and supports the BWX extension. Note Print verbose information about optimizations, such as certain transformations, more detailed messages about decisions etc. It requires a linker with linker plugin support for basic functionality. Instead use an additional -g level option to change the debug level for DWARF. March= ISA-string Generate code for given RISC-V ISA (e. rv64im). Mthumb-interwork Generate code that supports calling between the ARM and Thumb instruction sets. If the conflict table for a function could be more than the size in MB given by this parameter, the register allocator instead uses a faster, simpler, and lower- quality algorithm that does not require building a pseudo-register conflict table. User shumana chowdhury. It can be explicitly disabled by specifying -mno-zdcbranch. 0. as the service seems to keep resetting itself.
The use of "CONST16" is enabled by default only if the "L32R" instruction is not available. Currently the optimizations include specialization of division operations using the knowledge about the value of the denominator. The choices for unit are: 387 Use the standard 387 floating-point coprocessor present on the majority of chips and emulated otherwise. For example, code using the standard ISA encoding cannot jump directly to MIPS16 or microMIPS code; it must either use a call or an indirect jump. 5 wlh4 One 16x16 multiplier, blocking, sequential. Pca56 21164pc 21164PC Schedules as an EV5 and supports the BWX and MAX extensions. Note that some linkers, including newer versions of the GNU linker, can create multiple GOTs and sort GOT entries. That allows code to run on hardware variants that lack these registers. 7 of the RX62N Group User's Manual for more information). Two options are available: libstdc++ (the default, native C++ runtime for G++) and libc++ which is the C++ runtime installed on some operating systems (e. Darwin versions from Darwin11 onwards). No-canonical-prefixes Do not expand any symbolic links, resolve references to /.. / or /. K6 AMD K6 CPU with MMX instruction set support. Mloongson-ext -mno-loongson-ext Use (do not use) the MIPS Loongson EXTensions (EXT) instructions. For more information about this issue, see Commands.
To maintain whole program optimization, it is recommended to link such objects into static library instead. Gas-loc-support Inform the compiler that the assembler supports "" directives. Qwe123@localhost:3306/hedgedoc. Unroll-jam-min-percent The minimum percentage of memory references that must be optimized away for the unroll-and-jam transformation to be considered profitable. If the new base gets stored in a compressed register, then the new load/store can be compressed. Directories specified with -iquote apply only to the quote form of the directive, "#include "file"".
For example, -MT '$(objpfx)foo. Mno-ep -mep Do not optimize (do optimize) basic blocks that use the same index pointer 4 or more times to copy pointer into the "ep" register, and use the shorter "sld" and "sst" instructions. Fdiagnostics-parseable-fixits Emit fix-it hints in a machine-parseable format, suitable for consumption by IDEs.
