This change adds a GN template which creates a size report card across a set of different toolchains. The toolchains are defined in a build variable, each with an optional linker script and Bloaty config. The size report template builds a base and diff executable with each of the toolchains and compares the size difference of each. Example output for the host target: simple_bloat_toolchain ────────────────────── ┌───────────┬─────────┬────────┬───────┬───────┐ │ Label │ Segment │ Before │ Delta │ After │ ├═══════════┼═════════┼════════┼═══════┼═══════┤ │ gcc -Og │ CODE │ 413 │ +32 │ 445 │ │ │ RAM │ 576 │ +8 │ 584 │ ├───────────┼─────────┼────────┼───────┼───────┤ │ gcc -Os │ CODE │ 429 │ +16 │ 445 │ │ │ RAM │ 576 │ +8 │ 584 │ ├───────────┼─────────┼────────┼───────┼───────┤ │ gcc -O2 │ CODE │ 429 │ +32 │ 461 │ │ │ RAM │ 576 │ +8 │ 584 │ ├───────────┼─────────┼────────┼───────┼───────┤ │ clang -Og │ CODE │ 448 │ +32 │ 480 │ │ │ RAM │ 113 │ +15 │ 128 │ ├───────────┼─────────┼────────┼───────┼───────┤ │ clang -Os │ CODE │ 432 │ +16 │ 448 │ │ │ RAM │ 113 │ +15 │ 128 │ ├───────────┼─────────┼────────┼───────┼───────┤ │ clang -O2 │ CODE │ 448 │ +80 │ 528 │ │ │ RAM │ 113 │ +15 │ 128 │ └───────────┴─────────┴────────┴───────┴───────┘ Change-Id: I2c65f4d4f61354b9779628f207297eacd04470b9 |
