The LG_VADDR detection block accumulated duplicated logic and the rdtscp feature probe was interleaved with virtual-address-bit detection. Consolidate the detection: - Wrap the whole case in a single "if LG_VADDR = detect" guard instead of repeating it in every "case" section. - Define LG_VADDR exactly once, after the case. - Check the cache variable directly for the x86_64 error path. - Move the rdtscp probe into its own x86_64 case so it stays independent of LG_VADDR detection (it must run even when --with-lg-vaddr is given). There is no functional change. Verified on x86_64 that LG_VADDR and JEMALLOC_HAVE_RDTSCP are identical to before for auto-detection, and that --with-lg-vaddr still probes rdtscp. |

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: https://jemalloc.net/
