/* Handle the .section pseudo-op. This code supports two different
|
|

syntaxes.
|
|

|
|
|
|
|
The first is found on Solaris, and looks like
|
|
|
|
.section ".sec1",#alloc,#execinstr,#write
|
|
|
|
Here the names after '#' are the SHF_* flags to turn on for the
|
|
|
|
section. I'm not sure how it determines the SHT_* type (BFD
|
|
|
|
doesn't really give us control over the type, anyhow).
|
|
|
|
|
|
|
|
The second format is found on UnixWare, and probably most SVR4
|
|
|
|
machines, and looks like
|
|
|
|
.section .sec1,"a",@progbits
|
|
|
|
The quoted string may contain any combination of a, w, x, and
|
|
|
|
represents the SHF_* flags to turn on for the section. The string
|
|
|
|
beginning with '@' can be progbits or nobits. There should be
|
|
|
|
other possibilities, but I don't know what they are. In any case,
|
|
|
|
BFD doesn't really let us set the section type. */
