Daco Harkes b1e59721d4 Revert "[vm] Remove tcmalloc and malloc profiler." ... This reverts commit c67fac9cb4. Reason for revert: Regresses `dart:io` performance and causes failures. https://github.com/dart-lang/sdk/issues/51639 Original change's description: > [vm] Remove tcmalloc and malloc profiler. > > The standalone VM originally began statically linking tcmalloc to work around bugs in the system malloc for Fiber. Later it used tcmalloc's hooks to implement a profiler, but this is rarely used since it is only available in debug mode, misses early allocations, and often misses late allocations from an exhausted sample buffer. Removing it altogether avoids build complexity around which combinations of compiler/architecture/sysroot support tcmalloc, and reduces binary size. > > TEST=ci > Change-Id: I4b259e18b82b2d12a2a60962aabf83bd8d997d19 > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/286120 > Reviewed-by: Ben Konyi <bkonyi@google.com> > Commit-Queue: Ryan Macnak <rmacnak@google.com> Change-Id: I4395edd6f5bd7e26b4e38f4d931ad2ea67afba18 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/286925 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by: Slava Egorov <vegorov@google.com> Commit-Queue: Daco Harkes <dacoharkes@google.com>		2023-03-06 10:28:33 +00:00
