GCC: generate ARM assembler

[Glenn Møller-Holst]

Hi!

How do I get generated ARM assembler from this compiler:

#arm-elf-gcc -dumpversion
4.2.0
#arm-elf-gcc -dumpmachine
arm-elf

kind regards,

Glenn

arm-elf-gcc -S source.c

Maybe before playing with assembler you may check some magical utilities
like: ... man ... info ... ;-)

Hi Laurent

Very funny. PS: I am rather new to gcc and make:

#info arm-elf-gcc
(a lot of non-informative information)
# man arm-elf-gcc
No manual entry for arm-elf-gcc
#


The documentatation is bloated with options:
http://gcc.gnu.org/onlinedocs/gcc-4.2.3/gcc/
- and this just for gcc - what then about arm-elf-gcc?

That was why I thought it was better to ask here.

Where is the best place for option "-S" in the makefile?:
"...

# ELF-file contains debug information, or not
# (possible values for DEBUG are 0 or 1)
# Extra debug flags can be specified in DBFLAGS
DEBUG = 1
#DBFLAGS =

# Optimization setting
# (-Os for small code size, -O2 for speed)
OFLAGS = -Os

# Extra general flags
# For example, compile for ARM / THUMB interworking (EFLAGS =
-mthumb-interwork)
EFLAGS =

# Program code run in ARM or THUMB mode
# Can be [ARM | THUMB]
CODE = ARM

# List C source files here.
CSRCS = main.cpp

# List assembler source files here
ASRCS =
...."

kind regards,

Glenn

Does work here. Maybe your installation is incomplete. You could also try if
arm-elf-man exists.

arm-elf-gcc _is_ gcc.

Actually, it's not. What does ARM assembler have to do with the C++
programming language? Also note that this newsgroup is not about any
specific tools, but only about the language itself. A better newsgroup
would be gnu.gcc.help.

This is even more off-topic.
