General assembler options for Hitachi SH
To
use the GNU assembler, as,
to assemble gcc
output, configure gcc
with the switch, --with-gnu-as
(in GNUPro Toolkit distributions) or with the option, -mgas,
described in the following discussion.
For example, in the following
commandline, the assembler option, -ahl
requests a listing with interspersed high-level language and assembly language.
$ sh-hms-gcc -g -O -Wa,-alh,-L file.c
-L preserves local labels while the compiler debugging option, -g, gives the assembler the necessary debugging information.
Assembler options for listing output for Hitachi SH
Use the following options
to enable listing output from the assembler (the letters after ‘-a’
may be combined into one option, such as -aln):
-ah
Request a high-level language
listing.
-al
Request an output-program
assembly listing.
-as
Request a symbol table listing.
-ad
Omit debugging directives

assembler directives to control the appearance of the listing output (if
you do not request listing output with one of the -a

after the title line) when generating assembly listings.
