In master and gcc-8-branch:

grep -ri raise_nodefer_with_msg gcc/ada
gcc/ada/gcc-interface/trans.c:      (get_identifier 
("__gnat_raise_nodefer_with_msg"), NULL_TREE, ftype,

In gcc-7-branch:

grep -ri raise_nodefer_with_msg gcc/ada
gcc/ada/a-exexpr.adb:   pragma Export (C, Propagate_Continue, 
"__gnat_raise_nodefer_with_msg");
gcc/ada/gcc-interface/trans.c:      (get_identifier 
("__gnat_raise_nodefer_with_msg"), NULL_TREE, ftype,
gcc/ada/a-except.adb:   pragma Export (C, Raise_Current_Excep, 
"__gnat_raise_nodefer_with_msg");

It seems the a-except.adb was replaced by  a-except-2005.adb in this commit:

             * a-cfdlli.adb, a-cfdlli.ads (Formal_Model): Adapt to
             modifications in functional containers.
             * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads 
Reformat
             to improve readablity. Subprograms are separated between basic
             operations, constructors and properties. Universally quantified
             formulas in contracts are factorized in independant functions
             with a name and a comment.  Names of parameters are improved.

     2017-04-27  Gary Dismukes  <dismukes@adacore.com>

             * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.

     2017-04-27  Hristian Kirtchev  <kirtchev@adacore.com>

             * sem_res.adb (Resolve_Type_Conversion): Do not
             install a predicate check here since this is already done 
during
             the expansion phase. Verify whether the operand satisfies the
             static predicate (if any) of the target type.
             * sem_ch3.adb (Analyze_Object_Declaration): Do
             not install a predicate check if the object is initialized by
             means of a type conversion because the conversion is subjected
             to the same check.

     2017-04-27  Tristan Gingold  <gingold@adacore.com>

             * raise.c (__gnat_builtin_longjmp): Remove.
             (__gnat_bracktrace):
             Add a dummy definition for the compiler (__gnat_eh_personality,
             __gnat_rcheck_04, __gnat_rcheck_10) (__gnat_rcheck_19,
             __gnat_rcheck_20, __gnat_rcheck_21) (__gnat_rcheck_30,
             __gnat_rcheck_31, __gnat_rcheck_32): Likewise.
             * a-exexpr.adb: Renamed from a-exexpr-gcc.adb
             * a-except.ads, a-except.adb: Renamed from a-except-2005.ads
             and a-except-2005.adb.
             * raise-gcc.c: Allow build in compiler, compiled as a C++
             file.
             (__gnat_Unwind_ForcedUnwind): Adjust prototype.
             (db): Constify msg_format.
             (get_call_site_action_for): Don't use void arithmetic.
             * system.ads (Frontend_Exceptions): Set to False.
             (ZCX_By_Default): Set to True.
             (GCC_ZC_Support): Set to True.
             * gcc-interface/Makefile.in: No more variants for 
a-exexpr.adb and
             a-except.ad[sb].
             * gcc-interface/Make-lang.in: Add support for backend zcx 
exceptions
             in gnat1 and gnatbind.
             * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, 
s-addima.o,
             s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o
             * s-excmac.ads, s-excmac.adb: Copy of variants.
             * a-except.o: Adjust preequisites.
             Add handling of s-excmac-arm.adb and s-excmac-gcc.adb.
