While ARMC6 does use the same linker (armlink) as ARM Compiler 5, it
is not compatible.
The reason for this incompatibility are twofold:
* armlink may invoke the C preprocessor by adding a shebang
(`#!`) to the top of their input files.
* ARMC6 and ARMC5 differ in how you invoke the preprocessor:
* ARMC5: `#! armcc -E`
* ARMC6: `#! armclang -E`
This forces the tools to rewrite the shebang if it's wrong.
This does not yet handle dependencies properly
inc paths might be a list or might not be (just single string). If they don't, we are ending up with non valid include paths (one letter include paths).
This as result would not compile.
targets.json contained a key for some targets, `OUTPUT_EXT`, which I
moved to `Target`, the root of all targets. Following on that, the tools
now use this extension provided by `OUTPUT_EXT` to determine the file
type of the output executable.
An earlier patch in this series relies on the assumption that all
toolchain construction goes through `prepare_toolchain`. This is still
not the case. The only remaining user of the `mbedToolchain` object that
does not go through `prepare_toolchain` is the static analysis scanner.
It's basically dead-code at this point. I say we remove it. So this
patch removes it.
This is a bug fix for the following bug (Github issue #437):
If two builds were run specifying a non-default build folder, the second
build would fail to link with duplicate symbols and may not fit on the
device. The root of this problem is that these non-default build folders
are not ignored by scan-resources, and therefore included in the build.
We fix this bug by ignoring the build directory passed into the tools.
Resolves the github issue #3790: Blinky fails to build (on Mac) after
addition of linker script preprocessing feature. Paraphrasing, this
issue is that Homebrew on mac does not install `arm-none-eabi-gcc` in
the same location as `arm-none-eabi-cpp`, the C Pre-Processor. The tools
prior to this commit, and after turning on the pre-processing of the
linker-script will fail on any Mac homebrew installed toolchains.
This commit resolves the above issue by allowing the toolchain's path to
the executable to remain empty after a call to `check_executable`. When
this path is empty, the tools will search the PATH environment variable
for the executable.
This allows us to define parts of the linker script outside of the
linker script itself. In particular, we are interested in restricting
ROM to a subsection.
* Adding Cortex-A support for gnuarmeclipse
* Preventing '-mthumb' from being added to Cortex-A builds.
Previously, both '-mthumb' and '-marm' were being supplied to the
compiler (in that order). Because '-marm' came last, the compiler
respected this option. This change makes it so '-mthumb' is added for
all 'Cortex-M' targets only.
* Renaming to capital .S for Eclipse compatibility
On the ARM toolchain linker flags specified in the build profile do
not get passed to armlink. This patch adds these flags to the
arguments sent to armlink.
Before the toolchains would ignore error messages that contained the
string "Fatal error". This would lead to a silent failure unless the
compile command was ran with verbose options. This is now fixed.
This fixes an issue where the absolute path causes a file error if the
compiler paths are configured incorrectly. It uses a relative path
instead now (the files appears to be in the default search path).
This makes use of the reports generated by the building of tests to
prevent output from interleaving when the build is parallelized. This
required some changes to memap to return a generated string from
the 'generate_output' function. I also had an option to stop the prints
from memap to prevent text from interleaving
The 'silent' option has always been present in the toolchains API, however
it did not actually stop anything from being printed. Instead, it just
changed what was added to the build log. This make the 'silent' stop all
prints, but ensures that the output for the toolchain is still preserved
and accessible via the 'get_output' function.
This functionality was already present in the ARM toolchain script, but
this commit adds this across all toolchain scripts. Solves an issue that
cropped up where a build error wasn't being printed unless the verbose
flag was used. This should now print any existing error messages that have
been printed when the compiler output is being parsed.
This commit fixes an issue where the output from memap.py was not
consistent across all output formats. This issue stemmed from the fact
that a few important calculations were being performed at output
generation time. This has been moved to the 'parse' function and saved for
future use by the 'generate' functions.
Because this commit saves more data to the MemapParser instance, there
were some name collisions. The public member 'mem_summary' has been
renamed to 'mem_report'. 'mem_report' contains the data structure used by
the json generator. This includes both the section data and the memory
summary. The 'mem_summary' member now just contains the summary. The
summary includes total allocated heap, total static RAM, etc.
