Alexei Frolov	0944784e8e	Minor pw_bloat updates ... This change renames the bloat_report template to pw_size_report as it is more explicit. Additionally, the option to override the global Bloaty config file on a per-report basis is removed. This is due to Pigweed's policy of having one target per build invocation. The Bloaty config is inherently tied to an executable build target and linker script, both of which are provided by the target. Overriding the Bloaty config without changing the target can result in meaningless report output. Change-Id: I1fa444d065d964a3a85ade50039e06ae807050f2	2019-11-15 23:23:26 +00:00
Alexei Frolov	4c035b0487	Integrate bloat reports into docgen ... This change updates the bloat script to output an RST version of its report card table. Metadata is added to the bloat_report GN template indicating its RST output, allowing it to be listed as a dependency of pw_doc_group targets.

Alexei Frolov	e2016763a8	Add pw_bloat module ... This change adds a size reporting module named pw_bloat. The module uses Bloaty McBloatface to generate size report cards for binaries. It provides a GN template which defines an action to perform a size diff on a group of binary targets. Example output: simple_bloat ──────────── ┌────────────────┬──────────────┬────────┬───────┬───────┐ │ Label │ Segment │ Before │ Delta │ After │ ├════════════════┼══════════════┼════════┼═══════┼═══════┤ │ Add a loop │ EXAMPLE CODE │ 429 │ +32 │ 461 │ │ │ EXAMPLE RAM │ 576 │ +8 │ 584 │ ├────────────────┼──────────────┼────────┼───────┼───────┤ │ Add a function │ EXAMPLE CODE │ 429 │ +16 │ 445 │ │ │ EXAMPLE RAM │ 576 │ +8 │ 584 │ └────────────────┴──────────────┴────────┴───────┴───────┘ Change-Id: I14b3d383ec450bc6d017bf5d0111e266b0a3c368	2019-11-14 14:29:28 -08:00
