Subject: [PATCH v2 00/11] perf metric fixes and test

Add a test that all perf metrics (for your architecture) are
parsable. Fix bugs in the expr parser and in x86 metrics. Untested on
architectures other than x86.

v2 adds Fixes tags to commit messages for when broken metrics were
  first added. Adds a debug warning for division by zero in expr, and
  adds a workaround for id values in the expr test necessary for
  powerpc. It also fixes broken power8 and power9 metrics.

Ian Rogers (11):
  perf expr: unlimited escaped characters in a symbol
  perf metrics: fix parse errors in cascade lake metrics
  perf metrics: fix parse errors in skylake metrics
  perf expr: allow ',' to be an other token
  perf expr: increase max other
  perf expr: parse numbers as doubles
  perf expr: debug lex if debugging yacc
  perf metrics: fix parse errors in power8 metrics
  perf metrics: fix parse errors in power9 metrics
  perf expr: print a debug message for division by zero
  perf test: add expr test for pmu metrics
