Divide this in three sed scripts + instead: a one liner that removes the trailing spaces, one for + #defines, and then the last for #undef. + + The real speed up comes from the fact that the #define script + starts by checkin if the current input line has a #define, and if + not the script immediately goes to the next line, without running + the rest of the script as was the case before. Equally for the + #undef script. + + Note that this way, users that don't use #define templates don't + pay too much the overhead, since the sed script `realizes' quickly + there are no #define lines. My test case runs in 0.32s with + #define templates, and 0.24s without. To improve this common + case, the whole code for #define templates is conditionalized by a + proper egrep call. The result runs is 0.24s, i.e., almost no cost + at all. + + I made one dangerous change that I carefully evaluated before + commiting: the sed scripts are cut at 48 lines instead of 12 as + before. This produces here docs of about 4Kb. I checked many + `configure's and they all have big here documents, much bigger + than the 12 lines (for instance AC_FUNC_MMAP produces a 150 lines + long, 3800+ character here document). So I moved to the well + known HP UX sed limitations: no more than 100 commands, and there + are two commands per line now, plus a two command preamble. The + speed up is noticeable. + + * acgeneral.m4 (AC_OUTPUT_HEADERS): Remove the ac_e + family. + Changed ac_uD and ac_dD to `...;t t', instead of `...g'. + Instead of creating `conftest.vals' with both ac_e, ac_d, + and ac_u family, preprocess to strip the trailing spaces, and + create `conftest.defines' with the ac_d family, and then + `conftest.undefs' for the ac_e family. + Break up both `conftest.defines' and `conftest.undefs'.
