Hello,
bootstrapped on gcc master x86_64 and no extra failures generated on all front ends. Would this be ok for trunc? regards, Gaius Allow front ends to register spec functions gcc/{gcc.cc,gcc.h} [PR108261] This patch allows front ends to register spec functions. It is motivated by PR108261 which needs to retain the order of search path related options in the modula-2 front end. gcc/ChangeLog: * gcc.cc (add_spec_function): * gcc.h (add_spec_function): diff --git a/gcc/gcc.cc b/gcc/gcc.cc index becc56051a8..93e4e38389d 100644 --- a/gcc/gcc.cc +++ b/gcc/gcc.cc @@ -46,6 +46,7 @@ compilation is specified by a string called a "spec". */ #include "spellcheck.h" #include "opts-jobserver.h" #include "common/common-target.h" +#include <vector> @@ -1774,6 +1775,8 @@ static const struct spec_function static_spec_functions[] = { 0, 0 } }; +static std::vector<struct spec_function *>lang_spec_functions; + static int processing_spec_function; /* Add appropriate libgcc specs to OBSTACK, taking into account @@ -6825,9 +6828,25 @@ lookup_spec_function (const char *name) if (strcmp (sf->name, name) == 0) return sf; + for (auto *sf : lang_spec_functions) + if (strcmp (sf->name, name) == 0) + return sf; + return NULL; } +/* Add a new spec function. */ + +void +add_spec_function (const char *name, + const char *(*func) (int, const char **)) +{ + struct spec_function *sf = XNEW (struct spec_function); + sf->name = name; + sf->func = func; + lang_spec_functions.push_back (sf); +} + /* Evaluate a spec function. */ static const char * diff --git a/gcc/gcc.h b/gcc/gcc.h index 19a61b373ee..f40de0f5520 100644 --- a/gcc/gcc.h +++ b/gcc/gcc.h @@ -73,6 +73,8 @@ struct spec_function extern int do_spec (const char *); extern void record_temp_file (const char *, int, int); extern void set_input (const char *); +extern void add_spec_function (const char *name, + const char *(*func) (int, const char **)); /* Spec files linked with gcc.cc must provide definitions for these. */
