# The Makefile composes the final FINAL_CFLAGS and FINAL_LDFLAGS using
# what is needed for Redis plus the standard CFLAGS and LDFLAGS passed.
# However when building the dependencies (Jemalloc, Lua, Hiredis, ...)
# CFLAGS and LDFLAGS are propagated to the dependencies, so to pass
# flags only to be used when compiling / linking Redis itself REDIS_CFLAGS
# and REDIS_LDFLAGS are used instead (this is the case of 'make gcov').
#
# Dependencies are stored in the Makefile.dep file. To rebuild this file
# Just use 'make dep', but this is only needed by developers.

Implement redisAtomic to replace _Atomic C11 builtin (#7707) Redis 6.0 introduces I/O threads, it is so cool and efficient, we use C11 _Atomic to establish inter-thread synchronization without mutex. But the compiler that must supports C11 _Atomic can compile redis code, that brings a lot of inconvenience since some common platforms can't support by default such as CentOS7, so we want to implement redis atomic type to make it more portable. We have implemented our atomic variable for redis that only has 'relaxed' operations in src/atomicvar.h, so we implement some operations with 'sequentially-consistent', just like the default behavior of C11 _Atomic that can establish inter-thread synchronization. And we replace all uses of C11 _Atomic with redis atomic variable. Our implementation of redis atomic variable uses C11 _Atomic, __atomic or __sync macros if available, it supports most common platforms, and we will detect automatically which feature we use. In Makefile we use a dummy file to detect if the compiler supports C11 _Atomic. Now for gcc, we can compile redis code theoretically if your gcc version is not less than 4.1.2(starts to support __sync_xxx operations). Otherwise, we remove use mutex fallback to implement redis atomic variable for performance and test. You will get compiling errors if your compiler doesn't support all features of above. For cover redis atomic variable tests, we add other CI jobs that build redis on CentOS6 and CentOS7 and workflow daily jobs that run the tests on them. For them, we just install gcc by default in order to cover different compiler versions, gcc is 4.4.7 by default installation on CentOS6 and 4.8.5 on CentOS7. We restore the feature that we can test redis with Helgrind to find data race errors. But you need install Valgrind in the default path configuration firstly before running your tests, since we use macros in helgrind.h to tell Helgrind inter-thread happens-before relationship explicitly for avoiding false positives. Please open an issue on github if you find data race errors relate to this commit. Unrelated: - Fix redefinition of typedef 'RedisModuleUserChangedFunc' For some old version compilers, they will report errors or warnings, if we re-define function type.

Use H/W Monotonic clock and updates to AE (#7644) Update adds a general source for retrieving a monotonic time. In addition, AE has been updated to utilize the new monotonic clock for timer processing. This performance improvement is **not** enabled in a default build due to various H/W compatibility concerns, see README.md for details. It does however change the default use of gettimeofday with clock_gettime and somewhat improves performance. This update provides the following 1. An interface for retrieving a monotonic clock. getMonotonicUs returns a uint64_t (aka monotime) with the number of micro-seconds from an arbitrary point. No more messing with tv_sec/tv_usec. Simple routines are provided for measuring elapsed milli-seconds or elapsed micro-seconds (the most common use case for a monotonic timer). No worries about time moving backwards. 2. High-speed assembler implementation for x86 and ARM. The standard method for retrieving the monotonic clock is POSIX.1b (1993): clock_gettime(CLOCK_MONOTONIC, timespec*). However, most modern processors provide a constant speed instruction clock which can be retrieved in a fraction of the time that it takes to call clock_gettime. For x86, this is provided by the RDTSC instruction. For ARM, this is provided by the CNTVCT_EL0 instruction. As a compile-time option, these high-speed timers can be chosen. (Default is POSIX clock_gettime.) 3. Refactor of event loop timers. The timer processing in ae.c has been refactored to use the new monotonic clock interface. This results in simpler/cleaner logic and improved performance.

But the compiler that must supports C11 _Atomic can compile redis code, that brings a lot of inconvenience since some common platforms can't support by default such as CentOS7, so we want to implement redis atomic type to make it more portable. We have implemented our atomic variable for redis that only has 'relaxed' operations in src/atomicvar.h, so we implement some operations with 'sequentially-consistent', just like the default behavior of C11 _Atomic that can establish inter-thread synchronization. And we replace all uses of C11 _Atomic with redis atomic variable. Our implementation of redis atomic variable uses C11 _Atomic, __atomic or __sync macros if available, it supports most common platforms, and we will detect automatically which feature we use. In Makefile we use a dummy file to detect if the compiler supports C11 _Atomic. Now for gcc, we can compile redis code theoretically if your gcc version is not less than 4.1.2(starts to support __sync_xxx operations). Otherwise, we remove use mutex fallback to implement redis atomic variable for performance and test. You will get compiling errors if your compiler doesn't support all features of above. For cover redis atomic variable tests, we add other CI jobs that build redis on CentOS6 and CentOS7 and workflow daily jobs that run the tests on them. For them, we just install gcc by default in order to cover different compiler versions, gcc is 4.4.7 by default installation on CentOS6 and 4.8.5 on CentOS7. We restore the feature that we can test redis with Helgrind to find data race errors. But you need install Valgrind in the default path configuration firstly before running your tests, since we use macros in helgrind.h to tell Helgrind inter-thread happens-before relationship explicitly for avoiding false positives. Please open an issue on github if you find data race errors relate to this commit. Unrelated: - Fix redefinition of typedef 'RedisModuleUserChangedFunc' For some old version compilers, they will report errors or warnings, if we re-define function type.
