PR modula2/114517 gm2 does not allow comparison operator hash in column one
This patch allows -fno-cpp to be supplied to gm2. Without this patch
it causes an ICE. The patch allows -fno-cpp to turn off cpp flags.
These are tested in m2.flex to decide whether a change of state is
allowed (enabling handling of #line directives).
gcc/ChangeLog:
PR modula2/114517
* doc/gm2.texi: Mention gm2 treats a # in the first column
as a preprocessor directive unless -fno-cpp is supplied.
gcc/m2/ChangeLog:
PR modula2/114517
* gm2-compiler/M2Options.def (SetCpp): Add comment.
(GetCpp): Move after SetCpp.
(GetLineDirectives): New procedure function.
* gm2-compiler/M2Options.mod (GetLineDirectives): New
procedure function.
* gm2-gcc/m2options.h (M2Options_GetLineDirectives): New
prototype.
* gm2-lang.cc (gm2_langhook_init_options): OPT_fcpp only
assert if !value.
* m2.flex: Test GetLineDirectives before changing to LINE0
state.
gcc/testsuite/ChangeLog:
PR modula2/114517
* gm2/cpp/fail/hashfirstcolumn2.mod: New test.
