From b9e05ed07a3d805f12effa6b86c41a9d9c13a1f1 Mon Sep 17 00:00:00 2001 From: "Paul E. Murphy" Date: Fri, 3 Jun 2016 15:44:12 -0500 Subject: Refactor part of math Makefile In order to support more types, the Makefile needs a few bits shuffled. F is explictly used as a placeholder to substitute for the appropriate type suffix. This removes the need to demangle _r suffixed objects. The variable libm-compat-calls is added to house any objects which are only built to provide compat symbols within libm. That is, no newly added type should ever attempt building these. Note, k_standard* files have been added there. By consensus they are deprecated; in practice, we haven't gotten there yet. New types would be added as noted in the comments preceding type-TYPE-{suffix,routines,yes} variables. However, some manual additions will still need to be done to add appropriate flags when building the various variants of libm-test.c for a new type. Likewise, test-ildoubl is renamed test-ildouble for consistency's sake. --- math/Makefile | 131 +++++++++++++++++++++++++++++++++------------------------- 1 file changed, 75 insertions(+), 56 deletions(-) (limited to 'math/Makefile') diff --git a/math/Makefile b/math/Makefile index 4f14181..925b8d4 100644 --- a/math/Makefile +++ b/math/Makefile @@ -42,50 +42,81 @@ libm-support = s_lib_version s_matherr s_signgam \ ftestexcept fegetround fesetround fegetenv feholdexcpt \ fesetenv feupdateenv t_exp fedisblxcpt feenablxcpt \ fegetexcept -libm-calls = e_acos e_acosh e_asin e_atan2 e_atanh e_cosh e_exp e_fmod \ -
