# Emulate the rules used by the GNU ld and gold linkers for merging input

# sections into output sections in executables and shared objects. From

# Ian Lance Taylor and Cary Coutant.

# gcc 4.3 generates the following sorts of section names when it

# needs a section name specific to a function:

#   .text.FN

#   .rodata.FN

#   .sdata2.FN

#   .data.FN

#   .data.rel.FN

#   .data.rel.local.FN

#   .data.rel.ro.FN

#   .data.rel.ro.local.FN

#   .sdata.FN

#   .bss.FN

#   .sbss.FN

#   .tdata.FN

#   .tbss.FN

#

# The GNU linker maps all of those to the part before the .FN,

# except that .data.rel.local.FN is mapped to .data, and

# .data.rel.ro.local.FN is mapped to .data.rel.ro.  The sections

# beginning with .data.rel.ro.local are grouped together.

#

# For an anonymous namespace, the string FN can contain a '.'.

#

# Also of interest: .rodata.strN.N, .rodata.cstN, both of which the

# GNU linker maps to .rodata.
