2019-11-07src: do not use `std::function` for `OnScopeLeave`Anna Henningsen
Using `std::function` adds an extra layer of indirection, and in particular, heap allocations that are not necessary in our use case here.

2019-10-16src: refine maps parsing for large pagesGabriel Schulhof
Multiple sections may be marked as "r-xp" and with the executable's path. We use the location of the `__nodetext` symbol added by the linker script to ensure that the range we retrieve from the maps file does indeed contain the Node.js text section.

2019-10-11src: fix largepages regressionGabriel Schulhof
During the addition of macOS support for large pages, a `memcpy` ended up under the wrong preprocessor directive. As a result, the newly allocated large pages were not initialized with a copy of the text section. Thanks to Suresh Srinivas <suresh.srinivas@intel.com>!

2019-08-20src: add large page support for macOSDavid Carlier
Proposal to bring the support for this platform. We assume the pse36 cpu flag is present for 2MB large page support present in recent years in mac line (not to be backported to 10.x anyway). Recommended better for mac production servers rather than casual mac books.

2019-08-19build: enable linux large pages LLVM lld linkage supportDavid Carlier
The custom linker script is compatible with GNU ld only. As such, providin a new expliciting option to redirect to a different one. lld seems unable to migrate this large section w/o segfaulting so providing only the base address anchor for now.

2019-07-30src: readlink("/proc/self/exe") -> uv_exename()Ben Noordhuis
This commit also adds error handling. A THP-enabled build terminated with an out-of-memory error on a system without /proc because it cast the -1 from readlink() to size_t (i.e. ULONG_MAX) and then tried to allocate a string of that size.
