OPTIONS:

--radix=<uint> - Print size in radix. Only 8, 10, and 16 are valid

  • Specify output format -A - System V format -B - Berkeley format -m - Darwin -m format -aarch64-neon-syntax - Choose style of NEON code to emit from AArch64 backend:

=generic

  • Print size in radix: -o - Print size in octal -d - Print size in decimal -x - Print size in hexadecimal -disable-spill-fusing - Disable fusing of spill code into instructions -enable-load-pre - -enable-misched - Enable the machine instruction scheduling pass. -enable-objc-arc-opts - enable/disable all ARC Optimizations -enable-tbaa - -exhaustive-register-search - Exhaustive Search for registers bypassing the depth and interference cutoffs of last chance recoloring -fatal-assembler-warnings - Consider warnings as error -format - Specify output format

=sysv

- System V format

=berkeley

- Berkeley format

=darwin

- Darwin -m format -help - Display available options (-help-hidden for more) -internalize-public-api-file=<filename> - A file containing list of symbol names to preserve -internalize-public-api-list=<list> - A list of symbol names to preserve -join-liveintervals - Coalesce copies (default=true) -l - When format is darwin, use long format to include addresses and offsets. -limit-float-precision=<uint> - Generate low-precision inline sequences for some float libcalls -mc-x86-disable-arith-relaxation - Disable relaxation of arithmetic instruction for X86 -mips16-constant-islands - MIPS: mips16 constant islands enable. -mips16-hard-float - MIPS: mips16 hard float enable. -mlsm - Enable motion of merged load and store -mno-ldc1-sdc1 - Expand double precision loads and stores to their single precision counterparts -no-discriminators - Disable generation of discriminator information. -nvptx-sched4reg - NVPTX Specific: schedule for register pressue -print-after-all - Print IR after each pass -print-before-all - Print IR before each pass -print-machineinstrs=<pass-name> - Print machine instrs -regalloc - Register allocator to use
