| void decide_function_section | ( | ) |
If not using flag_reorder_blocks_and_partition, decide early whether the current function goes into the cold section, so that targets can use current_function_section during RTL expansion. DECL describes the function.
References cgraph_get_node(), current_function_decl, first_function_block_is_cold, and NODE_FREQUENCY_UNLIKELY_EXECUTED.
| bool decl_binds_to_current_def_p | ( | ) |
Return true when references to DECL must bind to current definition in final executable. The condition is usually equivalent to whether the function binds to the current module (shared library or executable), that is to binds_local_p. We use this fact to avoid need for another target hook and implement the logic using binds_local_p and just special cases where decl_binds_to_current_def_p is stronger than binds_local_p. In particular the weak definitions (that can be overwritten at linktime by other definition from different object file) and when resolution info is available we simply use the knowledge passed to us by linker plugin.

| bool decl_replaceable_p | ( | ) |
A replaceable function or variable is one which may be replaced at link-time with an entirely different definition, provided that the replacement has the same type. For example, functions declared with __attribute__((weak)) on most systems are replaceable. COMDAT functions are not replaceable, since all definitions of the function must be equivalent. It is important that COMDAT functions not be treated as replaceable so that use of C++ template instantiations is not penalized.

| int elf_record_gcc_switches | ( | ) |
This function provides a possible implementation of the TARGET_ASM_RECORD_GCC_SWITCHES target hook for ELF targets. When triggered by -frecord-gcc-switches it creates a new mergeable, string section in the assembler output file called TARGET_ASM_RECORD_GCC_SWITCHES_SECTION which contains the switches in ASCII format. FIXME: This code does not correctly handle double quote characters that appear inside strings, (it strips them rather than preserving them). FIXME: ASM_OUTPUT_ASCII, as defined in config/elfos.h will not emit NUL characters - instead it treats them as sub-string separators. Since we want to emit NUL strings terminators into the object file we have to use ASM_OUTPUT_SKIP.

Emit a special section directive to indicate that this object file was compiled with -fsplit-stack. This is used to let the linker detect calls between split-stack code and non-split-stack code, so that it can modify the split-stack code to allocate a sufficiently large stack. We emit another special section if there are any functions in this file which have the no_split_stack attribute, to prevent the linker from warning about being unable to convert the functions if they call non-split-stack code.

| void output_constant | ( | ) |
Output assembler code for constant EXP, with no label. This includes the pseudo-op such as ".int" or ".byte", and a newline. Assumes output_addressed_constants has been done on EXP already. Generate exactly SIZE bytes of assembler data, padding at the end with zeros if necessary. SIZE must always be specified. SIZE is important for structure constructors, since trailing members may have been omitted from the constructor. It is also important for initialization of arrays from string constants since the full length of the string constant might not be wanted. It is also needed for initialization of unions, where the initializer's type is just one member, and that may not be as long as the union. There a case in which we would fail to output exactly SIZE bytes: for a structure constructor that wants to produce more than SIZE bytes. But such constructors will never be generated for any possible input. ALIGN is the alignment of the data in bits.

Follow the IDENTIFIER_TRANSPARENT_ALIAS chain starting at *ALIAS until we find an identifier that is not itself a transparent alias. Modify the alias passed to it by reference (and all aliases on the way to the ultimate target), such that they do not have to be followed again, and return the ultimate target of the alias chain.

We delay assemble_external processing until the compilation unit is finalized. This is the best we can do for right now (i.e. stage 3 of GCC 4.0) - the right thing is to delay it all the way to final. See PR 17982 for further discussion.

static |
Some targets delay some output to final using TARGET_ASM_FILE_END. As a result, assemble_external can be called after the list of externals is processed and the pointer set destroyed.
