# Symbols and sections are interpreted as regexp patterns.
#
# If no matching symbol is found, scan-symbol-section reports a FAILure.
#
# Usage:
#
# { dg-final { scan-symbol-section FILENAME SYMBOL SECTION } }
#
# Examples:
#
# // The my_var C symbol must be in the .data section (or in a .data._my_var section
# // if -ffunction-sections is in use).
# { dg-final { scan-symbol-section "my-test.s" {^_my_var$} {^\.data(\._my_var)?$} } }
#
# // All numbered functions (func1, func2, etc.) must be in the .text section
# // (and not in any other section like .text._func1).
# { dg-final { scan-symbol-section "my-test.s" {^_func[1-5]$} {^\.text$} } }
#
# Caveats:
#
# * Only ELF and Mach-O targets are supported. Other
# targets, like PE/COFF, might appear to work.
# * For Mach-O targets, the section name matched by scan-symbol-section has one
# of two forms:
# * The Mach-O segment name followed by a comma (',') followed by the Mach-O
# section name. For example, "__TEXT,__text". (There is no whitespace
# between the Mach-O segment name and the Mach-O section name.)
# * ".const", ".data", or ".text". For example, the .text assembler directive
# causes the section name to be ".text" (not "__TEXT,__text"). (However, a
# directive such as .section __TEXT,__text will cause the section name to be
# "__TEXT,__text".)
# * Because scan-symbol-section parses assembly code, scan-symbol-section is
# unaware of section rewriting performed by the linker. For example, the
# sections .text._f1 and .text._f2 would normally be merged by binutils'
# linker into one section called .text, but scan-symbol-section reports the
# sections as .text._f1 and .text._f2 (and not .text).
# * The symbol pattern matches any assembly label, including local labels which
# begin with `.L`.
