Ideally we want -O2. 5432N/A# Because LLVM's install target doesn't install everything that 5432N/A# -ftree-vectorize | -fno-tree-vectorize: 5432N/A# builds at some point in the future.. 5432N/A# -ftree-slp-vectorize | -fno-tree-slp-vectorize: 5432N/A# Less aggressive vectorization than -ftree-vectorize, but useful 5432N/A# in case -ftree-slp-vectorize misses some vectorization opportunities. 5432N/A# Documentation at the same URL as above. 5432N/A# builds at some point in the future. 5432N/A# -freorder-blocks | -fno-reorder-blocks 5432N/A# builds at some point in the future. 5432N/A# -ftoplevel-reorder | -fno-toplevel-reorder 5432N/A# Another BasiBlock depentent optimization option. 5432N/A# builds at some point in the future. 5432N/A# Enable stack smashing (stack corruption) protection and detection. 5432N/A# This flag should always be used in conjunction with -Wstack-protector. 5432N/A# -Wstack-protector acts at compile-time, -fstack-protector-all acts 5432N/A# This flag carries significant runtime overhead, but is very useful. 5432N/A# Always enabled for now. May be removed in the future. 5432N/A# -g3: Enable macro visibility in GDB. With just -g, debug builds will 5432N/A# not record the expanded values of macros. With -g3, the values of 5432N/A# expanded macros will be recorded, and macros will be observable in 5432N/A# Assume that the code does not make use of misaligned doubles on SPARC. 5432N/A# On SPARC, doubles must align on 8. This flag makes GCC assume that 5432N/A# there is no misaligned double use in the code, and GCC will not 5432N/A# is such broken code when using this flag, the program will SIGBUS 5432N/A# at runtime. This is a very useful debugging flag. 5432N/A# Use hardware floating-point operations when available. Compilers 5432N/A# generally make very little use of floating-point, but this is 5432N/A# floating-point operations are used. No-op for quad-floating-point 5432N/A# and UltraSPARC-1/2/3 because on those ISA's quad-floating-point 5432N/A# ops are always done in software. But quad-floating-point ops in a 5432N/A# compiler are virtually non-existent. 5432N/A# Tell GCC the size of a pointer on SPARC. 5432N/A# When used in addition to -shared on SPARC, this tells GCC to not pass 5432N/A# -z text to the linker when linking a shared object. 5432N/A# There is some suspicious interaction happening here between GCC/GAS 5432N/A# and the Sun linker. Technically, and in theory, this flag should not 5432N/A# be needed when compiling -fPIC. However, extensive documented use 5432N/A# and practice has shown that it is indeed needed. The disadvantage 5432N/A# of using this flag is that it triggers copy-on-write relocations. 5432N/A# available. Building for Opteron - which implies SSE2 - is adequate 5432N/A# Put this here for now until the gpatch problems are resolved. 5432N/A# use bash(1) to run the install recipes otherwise clang header installation 5432N/A# There are no master test results yet.
