Detailed Description

A class for writing rtx to a FILE *.   

Constructor & Destructor Documentation

◆ rtx_writer()

rtx_writer::rtx_writer ( FILE * outf,
int ind,
bool simple,
bool compact,
rtx_reuse_manager * reuse_manager )
Constructor for rtx_writer.   

Member Function Documentation

◆ finish_directive()

void rtx_writer::finish_directive ( )
Emit a closing parenthesis and newline.   

References m_outfile, and m_sawclose.

Referenced by print_param().

◆ operand_has_default_value_p()

bool rtx_writer::operand_has_default_value_p ( const_rtx in_rtx,
int idx )
Subroutine of rtx_writer::print_rtx.
In compact mode, determine if operand IDX of IN_RTX is interesting
to dump, or (if in a trailing position) it can be omitted.   

References GET_CODE, GET_RTX_FORMAT, m_compact, NULL, NULL_RTX, XEXP, and XSTR.

Referenced by print_rtx().

◆ print_rtl()

void rtx_writer::print_rtl ( const_rtx rtx_first)
External entry point for printing a chain of insns
starting with RTX_FIRST.
A blank line separates insns.

If RTX_FIRST is not an insn, then it alone is printed, with no newline.   

References as_a(), GET_CODE, m_outfile, NEXT_INSN(), print_rtx(), and print_rtx_head.

Referenced by print_rtl(), and print_simple_rtl().

◆ print_rtl_single_with_indent()

void rtx_writer::print_rtl_single_with_indent ( const_rtx x,
int ind )
Like print_rtl_single, except specify an indentation.   

References alloca, m_indent, m_outfile, m_sawclose, print_rtx(), and print_rtx_head.

Referenced by print_rtl_single(), and print_rtx_function().

◆ print_rtx()

◆ print_rtx_operand()

◆ print_rtx_operand_code_0()

void rtx_writer::print_rtx_operand_code_0 ( const_rtx in_rtx,
int idx )
Subroutine of print_rtx_operand for handling code '0'.
0 indicates a field for internal use that should not be printed.
However there are various special cases, such as the third field
of a NOTE, where it indicates that the field has several different
valid contents.

◆ print_rtx_operand_code_e()

void rtx_writer::print_rtx_operand_code_e ( const_rtx in_rtx,
int idx )
Subroutine of print_rtx_operand for handling code 'e'.
Also called by print_rtx_operand_code_u for handling code 'u'
for LABEL_REFs when they don't reference a CODE_LABEL.

int idx )

◆ print_rtx_operand_code_r()

◆ print_rtx_operand_code_u()

void rtx_writer::print_rtx_operand_code_u ( const_rtx in_rtx,
int idx )
Subroutine of print_rtx_operand for handling code 'u'.
