Bug ID: 60070
Summary: An option to disable all floating-pont
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: hpa at zytor dot com
In the Linux kernel, and quite possibly in other standalone/embedded
environments, the use of any floating-point state or instructions is an error.
It would be nice to have a single option to have gcc error out on any floating
point use, rather than having to chase options.

Like AARCH64: mgeneral-regs-only Target Report RejectNegative Mask(GENERAL_REGS_ONLY) Generate code which uses only the general registers I rather see this as a target specific option and not a single option as it is a target specific problem and some targets don't have floating point/vector registers. Also some targets having some support for having vector/floating point in the kernel. ^ permalink raw reply [flat|nested] 4+ messages in thread

I'm actually working on such a patch and should have soon something to show. ^ permalink raw reply [flat|nested] 4+ messages in thread

I don't know if this would be an useful option that is general though. Each target will implement it differently too. ^ permalink raw reply [flat|nested] 4+ messages in thread
