[PATCH RFC 0/1] tcg: add perfmap and jitdump

Posted by Ilya Leoshkevich 3 years, 3 months ago

Hi,

This is a rework of jitdump and perfmap patches from Vanderson and
Alex:

- jitdump: https://wiki.qemu.org/Features/TCGCodeQuality

  v1: https://lists.gnu.org/archive/html/qemu-devel/2019-08/msg02676.html
  v2: https://lore.kernel.org/qemu-devel/20190830121903.17585-1-vandersonmr2@gmail.com/
  v9: https://www.mail-archive.com/qemu-devel@nongnu.org/msg650269.html

- perfmap

  rfc: https://lists.nongnu.org/archive/html/qemu-devel/2014-03/msg05386.html
  v2: https://lists.gnu.org/archive/html/qemu-devel/2014-07/msg02061.html
  v3: https://lists.gnu.org/archive/html/qemu-devel/2014-07/msg04289.html
  v4: https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg00095.html

It addresses some of the feedback (among other things: symlink attacks,
Elf64_Ehdr on 32-bit hosts, flockfile, license headers, style) and adds
debuginfo support.

Best regards,
Ilya
