| 2020-03-09 | perf expr: Make expr__parse() return -1 on error | Jiri Olsa | 1 | -1/+1 | |
| To match the error value of the expr__find_other function, so all exported expr functions return the same values: 0 on success, -1 on error.

| 2020-03-09 | perf expr: Straighten expr__parse()/expr__find_other() interface | Jiri Olsa | 1 | -4/+4 | |
| Now that we have a flex parser we don't need to update the parsed string pointer, so the interface can just be passed the pointer to the expression instead of a pointer to pointer.

| 2020-03-09 | perf expr: Move expr lexer to flex | Jiri Olsa | 1 | -0/+93 | |
| Adding expr flex code instead of the manual parser code. So it's easily extensible in upcoming changes. The new flex code is in flex.l object and gets compiled like all the other flexers we use. It's defined as flex reentrant parser. It's used by both expr__parse and expr__find_other interfaces by separating the starting point. There's no intended change of functionality ;-) the test expr is passing.

| Add generic expr code into new expr.c object. The expr.c object will be mainly used in following change that will get rid of the manual flex code, Signed-off-by: Jiri Olsa <[email protected]> Reviewed-by: Andi Kleen <[email protected]> Cc: Alexander Shishkin <[email protected]> Cc: John Garry <[email protected]> Cc: Kajol Jain <[email protected]> Cc: Michael Petlan <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Ravi Bangoria <[email protected]> Link: http://lore.kernel.org/lkml/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]> | |||||
