Subject: [PATCH] Do not define tgmath.h fmaxmag, fminmag macros for C2X (bug
|
|
28397)
|
|
|
|
C2X does not include fmaxmag and fminmag. When I updated feature test
|
|
macro handling accordingly (commit
|
|
858045ad1c5ac1682288bbcb3676632b97a21ddf, "Update floating-point
|
|
feature test macro handling for C2X", included in 2.34), I missed
|
|
updating tgmath.h so it doesn't define the corresponding type-generic
|
|
macros unless __STDC_WANT_IEC_60559_BFP_EXT__ is defined; I've now
|
|
reported this as bug 28397. Adjust the conditionals in tgmath.h
|
|
accordingly.
|
|
|
|
Tested for x86_64.
