*	Replace gen-as-const.awk by gen-as-const.py.	Joseph Myers	2018-11-30	1	-63/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch replaces gen-as-const.awk, and some fragments of the Makefile code that used it, by a Python script. The point is not such much that awk is problematic for this particular script, as that I'd like to build up a general Python infrastructure for extracting information from C headers, for use in writing tests of such headers. Thus, although this patch does not set up such infrastructure, the compute_c_consts function in gen-as-const.py might be moved to a separate Python module in a subsequent patch as a starting point for such infrastructure. The general idea of the code is the same as in the awk version, but no attempt is made to make the output files textually identical. When generating a header, a dict of constant names and values is generated internally then defines are printed in sorted order (rather than the order in the .sym file, which would have been used before). When generating a test that the values computed match those from a normal header inclusion, the test code is made into a compilation test using _Static_assert, where previously the comparisons were done only when the test was executed. One fragment of test generation (converting the previously generated header to use asconst_* prefixes on its macro names) is still in awk code in the makefiles; only the .sym processing and subsequent execution of the compiler to extract constants have moved to the Python script. Tested for x86_64, and with build-many-glibcs.py. * scripts/gen-as-const.py: New file. * scripts/gen-as-const.awk: Remove. * Makerules ($(common-objpfx)%.h $(common-objpfx)%.h.d): Use gen-as-const.py. ($(objpfx)test-as-const-%.c): Likewise.
