Illegal instruction
I've taken a look at the mimalloc-3.0.3 source. The setting
MI_OPT_ARCH=OFF in debian/rules appears to
invoke a falsehood if my interpretation of
mimalloc-3.0.3+ds/CMakeLists.txt is correct:
# Compiler and architecture specific flags
if(CMAKE_C_COMPILER_ID MATCHES "AppleClang|Clang|GNU|Intel" AND NOT
CMAKE_SYSTEM_NAME MATCHES "Haiku")
# ^true
if(MI_OPT_ARCH)
# ^false - go to continue...
if(APPLE AND CMAKE_C_COMPILER_ID MATCHES "AppleClang|Clang" AND
CMAKE_OSX_ARCHITECTURES) # to support multi-arch binaries (#999)
if("arm64" IN_LIST CMAKE_OSX_ARCHITECTURES)
list(APPEND MI_OPT_ARCH_FLAGS "-Xarch_arm64;-march=armv8.1-a")
endif()
if("x86_64" IN_LIST CMAKE_OSX_ARCHITECTURES)
list(APPEND MI_OPT_ARCH_FLAGS
"-Xarch_x86_64;-march=haswell;-Xarch_x86_64;-mavx2")
endif()
# continue...
elseif(MI_ARCH STREQUAL "x64")
# ^true. Architecture is x86-64
set(MI_OPT_ARCH_FLAGS "-march=haswell;-mavx2") # fast bit scan
(since 2013)
# ^These flags force Haswell architecture or above and allow the
generation of AVX2 code
elseif(MI_ARCH STREQUAL "arm64")
set(MI_OPT_ARCH_FLAGS "-march=armv8.1-a") # fast atomics
(since 2016)
endif()
endif()
endif()
-march other than 'x86-64' should not be used if one intends to
generate universal x86-64 instructions:
<https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html>
-mtune=haswell would be OK.
A quick fix for x86-64 should be to patch this line (maybe upstream?):
set(MI_OPT_ARCH_FLAGS "-march=haswell;-mavx2") # fast bit scan (since 2013)
with:
set(MI_OPT_ARCH_FLAGS "-mtune=haswell")
(Although I'd probably choose "-mtune=sandybridge" because Sandy
Bridge is still architecturally
similar to present day processors but has some stalls that can be
worked around without unduly impacting
newer processor architectures).
MI_OPT_ARCH=OFF appears to be an insufficient workaround to this
now-closed bug report:
