Fix for incorrect breakpoint set in case of flang compiled binary
Currently, GDB is not able to set a breakpoint at subprogram post
prologue for flang generated binaries. This is due to clang having
two line notes one before and another after the prologue.
Now the end of prologue is determined using symbol table, which was
the way for clang generated binaries already. Since clang and flang
both share same back-end it is true for flang as well.
gdb/ChangeLog
* amd64-tdep.c (amd64_skip_prologue): Using symbol table
to find the end of prologue for flang compiled binaries.
* arm-tdep.c (arm_skip_prologue): Likewise.
* i386-tdep.c (i386_skip_prologue): Likewise.
* producer.c (producer_is_llvm): New function.
(producer_parsing_tests): Added new tests for clang/flang.
* producer.h (producer_is_llvm): New declaration.
gdb/testsuite/ChangeLog
* gdb.fortran/vla-type.exp: Skip commands not required for
the Flang compiled binaries after prologue fix.
