2019-01-30Purge linker block allocators before leaving linkerVic Yang
This is the second attempt to purge linker block allocators. Unlike the previously reverted change which purge allocators whenever all objects are freed, we only purge right before control leaves the linker. This limits the performance impact to one munmap() call per dlopen(), in most cases. Bug: 112073665 Test: Boot and check memory usage with 'showmap'. Test: Run camear cold start performance test.

2019-01-29Revert "linker: Purge block allocator memory when possible"Vic Yang
This reverts commit fb78a4ac1b93218f59aa44089ae5f4dbfababf0d. Reason for revert: Performance regression. Change-Id: Ib12335fc7478dad933da00b8bc525366c9330a17
2019-01-25Move the linker allocator into libcRyan Prichard
Rename LinkerMemoryAllocator -> BionicAllocator Rename LinkerSmallObjectAllocator -> BionicSmallObjectAllocator libc and the linker need to share an instance of the allocator for allocating and freeing dynamic ELF TLS memory (DTVs and segments). The linker also continues to use this allocator.

2019-01-23linker: Purge block allocator memory when possibleVic Yang
If all allocated memory from a block allocator is freed, it is a good opportunity to purge all the pages allocated to reduce lingering dirty pages. Memory saving varies with the platform and what processes are running. Measuring right after boot, this saves ~1.8MB on cuttelfish and ~1.3MB on a 32-bit ARM device. Bug: 112073665 Test: Boot and check memory usage with 'showmap'. Change-Id: I53769e0ec9699f0b3645cdf281a2c0bbffb98676
2018-10-25Clean up bionic_macros.h a bit.Elliott Hughes
Use <android-base/macros.h> instead where possible, and move the bionic macros out of the way of the libbase ones. Yes, there are folks who manage to end up with both included at once (thanks OpenGL!), and cleaning that up doesn't seem nearly as practical as just making this change. Bug: N/A Test: builds Change-Id: I23fc544f39d5addf81dc61471771a5438778895b
