Fork of Go programming language with my patches. http://git.kilabit.info/go/atom?h=makepkg 2026-01-13T17:52:54Z 2026-01-13T17:52:54Z Michael Matloob matloob@golang.org 2026-01-12T19:37:39Z urn:sha1:e2fef50def98b87107ab963f657d43d7869b8463 This makes it easier to identify which functions are used for memory allocation by looking for functions that start with mallocgc. The Size suffix is added so that the isSpecializedMalloc function in cmd/compile/internal/ssa can distinguish between the generated functions and the mallocgcTiny function called by mallocgc, similar to the SC suffixes for the mallocgcSmallNoScanSC* and mallocgcSmallScanNoHeaderSC* functons.

(That's the limit where it's possible to end up in the no header case when there are scan bits, and where the benefits of the specialized functions significantly diminish according to microbenchmarks). If the specializedmalloc GOEXPERIMENT is turned on, mallocgc will call one of these functions in the no header case. malloc_generated.go is the generated file containing the specialized malloc functions. malloc_stubs.go contains the templates that will be stamped to create the specialized malloc functions. malloc_tables_generated contains the tables that mallocgc will use to select the specialized function to call. I've had to update the two stdlib_test.go files to account for the new submodule mkmalloc is in. mprof_test accounts for the changes in the stacks since different functions can be called in some cases. I still need to investigate heapsampling.go.
