From f54d138e2cbabbfb6488a1605f995aaf4a663e0b Mon Sep 17 00:00:00 2001
From: Stephen Dolan <sdolan@janestreet.com>
Date: Tue, 23 Apr 2019 14:11:11 +0100
Subject: [PATCH 5/8] Use a more compact representation of debug information.
Locations of inlined frames are now represented as contiguous
sequences rather than linked lists.
The frame tables now refer to debug info by 32-bit offset rather
than word-sized pointer.
(cherry picked from commit b0ad600b88b3eb6e53be681794f36dd58b6a493d)

From dac12e5db7f4ca4a32b0eccea1d16d27f9df86d2 Mon Sep 17 00:00:00 2001
From: Stephen Dolan <sdolan@janestreet.com>
Date: Tue, 16 Jul 2019 16:24:01 +0100
Subject: [PATCH 6/8] Retain debug information about allocation sizes, for
statmemprof.
This code is adapted from jhjourdan's 2c93ca1e711. Comballoc is
extended to keep track of allocation sizes and debug info for each
allocation, and the frame table format is modified to store them.
The native code GC-entry logic is changed to match bytecode, by
calling the garbage collector at most once per allocation.
amd64 only, for now.
(cherry picked from commit 34f97941ec302129f516c926c9ef65e4d68b8121)

From 69eac75740fafad36246392c666410e9e66388d7 Mon Sep 17 00:00:00 2001

Subject: [PATCH 7/8] Use allocation-size info on more than just amd64.
Moves the alloc_dbginfo type to Debuginfo, to avoid a circular
dependency on architectures that use Branch_relaxation.
This commit generates frame tables with allocation sizes on all
architectures, but does not yet update the allocation code for
non-amd64 backends.
(cherry picked from commit 768dcce48f79c33beb2af342a4c3551c276afe11)
