Subject: [PATCH] Config.in.arch: Free UCLIBC_HAS_FPU setting from depending on UCLIBC_HAS_FLOATS
|
||||
|
||||
UCLIBC_HAS_FLOATS and UCLIBC_HAS_FPU are denoting two different aspects.
|
||||
UCLIBC_HAS_FLOATS covers the floating point operations which has nothing
|
||||
to do if you have FPU or not.

The "use BX" option is now a suggestion that BX be used if available.
|
||||
Use a macro to detect if BX is available at build time. If so, and
|
||||
the user requested it be used, then use it. Otherwise, error out.

Rely on the compiler to be properly setup for the default ABI.
|
||||
|
||||
When installing-headers, there are two cases:
|
||||
- NPTL: no issue, a cross-compiler is already expected
|
||||
- LinuxThreads: no issue, EABI/OABI has no impact on installed headers.

Rely on the compiler to be correctly set up to generate
|
||||
appropriate code for the target variant.
|
||||
|
||||
This exposes the Thumb option, as it is no longer auto-selected.
|
||||
The "Use BX" no longer depends on supported CPU to be selected,
|
||||
so it now defaults to 'n' as it shall work by default on CPUs
|
||||
that do not have BX.

Subject: [PATCH 2/7] ARM: introduce blind options to select & force THUMB mode
|
||||
Date: Sun, 9 Jan 2011 01:45:05 +0100
|
||||
Message-Id: <1294533910-19305-3-git-send-email-yann.morin.1998@anciens.enib.fr>
|
||||
X-Mailer: git-send-email 1.7.1
|
||||
In-Reply-To: <1294533910-19305-1-git-send-email-yann.morin.1998@anciens.enib.fr>
|
||||
References: <1294533910-19305-1-git-send-email-yann.morin.1998@anciens.enib.fr>
|
||||
|
||||
Add three new blind options to set use of Thumb mode:
|
||||
- COMPILE_IN_THUMB_MODE
|
||||
- if set, CFLAGS will contain -mthumb
|
||||
- if unset, the compiler's default is used
|
||||
- HAS_THUMB
|
||||
- CPUS with Thumb instruction set can select this
|
||||
- use of BX depends on this
|
||||
- FORCE_THUMB
|
||||
- CPUs that are Thumb-only must select this
|
||||
- this selects: HAS_THUMB, COMPILE_IN_THUMB_MODE and USE_BX
|
||||
|
||||
Also, remove leading space in Rules.mak.
